Answer:
The direct labor rate variance for November is $34,200
Explanation:
To find out the direct labor rate variance, we have to multiply the actual standard rate of direct labor into actual hours of direct labor used
Standard hourly rate of direct labor hour = $14.40
Actual direct labor hours = 5,000
Standard direct labor cost
= 5,000 × $14.40
= $72,000
Total factory wages are $42,000 in which direct labor is 90%
= $42,000 × 90%
= $37,800
Actual direct labor cost = $37,800
Therefore,
Direct labor rate variance = Standard direct labor cost - Actual direct labor cost
Direct labor rate variance
= $72,000 - $37,800
= $34,200
Kawamura, a careful utility maximizer, consumes peanut butter and ice cream. Assume that both peanut butter and ice cream are normal goods and that diminishing marginal utility applies to both goods. Right after he achieves the utility-maximizing level of consumption of the two goods, the price of peanut butter falls. After he adjusts to this event, the marginal utility of peanut butter goes _____ and that of ice cream goes _____.
Answer:
The marginal utility of peanut butter goes down and that of ice cream goes up.
Explanation:
The substitution effect states that when the price of a product falls, it will lead to a rise in the quantity demanded of the product as buyers will buy more of the product that is now relatively cheaper.
And as more of a good is bought, its marginal utility falls. And as less of a product is bought, its marginal utility increases.
Based on the above explanation therefore, the marginal utility of peanut butter goes down and that of ice cream goes up after Kawamura adjusts to the event.
This is because as more of peanut butter is bought due to the fall in its price, its marginal utility falls. And as less of ice cream is bought as it is now relatively more expensive, its marginal utility increases.
Workman Software has 11 percent coupon bonds on the market with 19 years to maturity. The bonds make semiannual payments and currently sell for 108.3 percent of par. a. What is the current yield on the bonds
Answer:
10.16%
Explanation:
Coupon amount = 11% * 1000
Coupon amount = $110
Price of bond = 1000*108.3%
Price of bond = $1,083
Current yield = Coupon amount / Price of bond
Current yield = $110 / $1,083
Current yield = 0.1015697
Current yield = 10.16%
So, the current yield on the bonds is 10.16%.
The following statements describe why profits for firms in a perfectly competitive industry tend to vanish in the long run. Select the explanation that most accurately reflects this scenario?
A) Firms try to increase supply to cover their costs if they experience losses, and this leads to zero profits.
B) Firms are unable to generate revenue over time because the demand for products drops.
C) When other perfectly competitive firms see an opportunity to earn profits and enter the market prices drop.
D) When other perfectly competitive firms see an opportunity to earn profits and enter the market, prices rise.
Answer:
The correct answer is the option C: When other perfectly competitive firms see an opportunity to earn profits and enter the market the prices drop.
Explanation:
To begin with, in the microeconomics theory the perfect competitive market is characterized by the fact that there a lot of companies that sell an homogenous product and that are price takers of the market itself. So therefore that the only big difference in the firms are the costs and the prices that they have. Moreover, in the long run the firms are obtaining great profits so that leads to the enter of another more companies to the market and the supply rises the prices will have to go low so that will implicate as well a decrease in the prices of every company that now works in that industry.
Given below are several ratios. Select the accounts or amounts that would be used in order to calculate the ratio. You will have more than one response to each ratio. Some accounts or amounts may not be used at all. (Select all that apply.) Debt-to-equity ratio a.Cash paid for acquisitions b.Interest expense c.Total dividends paid d.Cash flow from operations before interest and tax payments e.Total stockholders' equity f.Net income g.Total liabilities h.Cash flow from operations
Answer:
Total stockholders' equity.Total liabilities.Explanation:
The Debt to equity ratio shows the proportions of the financing options used to finance the operations of the company namely debt and equity.
It is calculated by the formula:
= Total liabilities / Total stockholders' equity * 100%
As shown by the formula , the relevant accounts are:
Total stockholders' equity.Total liabilities.If Fees Earned has been credited, it is most likely that:
A. a correcting entry for the overstatement of revenue was recorded. B. a customer paid in advance
C. services were provided.
D. the owner made an investment.
Answer:
C. services were provided.
Explanation:
If Fees Earned has been credited, it is most likely that: "services were provided."
For fees to be earned it means something must have been done in exchange for the fee. Considering this is a business-related issue, then it is correct to conclude that "If Fees Earned has been credited, it is most likely that: services were provided."
Option A is not correct because the overstatement of revenue is not related to the fee warmed being credited.
Option B is not correct, because a payment made in advance does not correlate to a fee earned. Option D is not correct as well, because an investment has nothing to do with a few earned.

Based on Interest Rate Parity, the forward premium for CAD should be exactly equal to: Group of answer choices 1.90% - 1.87% 1.02% 98.11%
Answer:
1.90%
Explanation:
Note that that CAD exchange rate would be in terms of how many US dollars can be exchanged for 1 CAD, which means that the formula for forward premium would be stated in terms of US dollars, I mean the US$ as the numerator and CAD's interest rate would be the denominator
the forward premium for CAD=((1+US interest rate)/(1+Canada interest rate))-1
the forward premium for CAD=((1+7%)/(1+5%))-1
the forward premium for CAD=1.90%
A researcher wants to test the order of integration of some time series data. He decides to use the DF test. He estimates a regression of the form
delta yt = mu + si yt-1 + mut
and obtains the estimate ˆ? = -0.02 with standard error = 0.31.
(a) What are the null and alternative hypotheses for this test?
(b) Given the data, and a critical value of -2.88, perform the test.
(c) What is the conclusion from this test and what should be the next step?
(d) Why is it not valid to compare the estimated test statistic with the corresponding critical value from a t-distribution, even though the test statistic takes the form of the usual t-ratio?
Answer:
a) H0: u = presence of a unit root
HA: u ≠ presence of a unit root ( i.e. stationary series )
b) t stat = -0.064
c) We will reject the Null hypothesis and the next step will be to accept the alternative hypothesis
d) It is not valid to compare the estimated t stat with the corresponding critical value because a random walk is non-stationary while the difference is stationary because it is white noise
Explanation:
a) stating the null and alternative hypothesis
H0: u = presence of a unit root
HA: u ≠ presence of a unit root ( i.e. stationary series )
b) performing the test
critical value = -2.88
T stat = coefficient / std error
= -0.02 / 0.31 = -0.064
c) From the test, the value of T stat > critical value we will reject the Null hypothesis hence the next step will be to accept the alternative hypothesis
d) It is not valid to compare the estimated t stat with the corresponding critical value because a random walk is non-stationary while the difference is stationary because it is white noise

At the fourth and final resource, one operator handles the product. No quality problems exist at this step and the processing time is 12 minutes per unit. For every unit of demand, how many units have to flow through the second step in the process
Answer:
2.25 units.
Explanation:
Processing time is 5 minutes per unit for step 1. The total capacity is 60 minutes then no. of units produced can be;
60 / 5 = 12 units per hour.
For second step processing time is 4 minutes per unit. There is 0.85 unit of product is scrapped. Then no. of units produced per hour can be ;
60 / 4 = 15 units per hour.
After scrap the net product units per hour will be;
15 units * [1 - 0.85] = 2.25 units per hour.

Q2. With the help of book please elaborate What is the difference between a corporate strategy and a competitive strategy? Give three examples of each. (Words limit up to 150)
Answer and Explanation:
Competitive and corporate strategy are very important for the success and good management of a business. Competitive strategy is one that allows a company to promote elements capable of making it different from its competitors. Examples of competitive strategy are offering lower prices, higher quality products and negotiation between customers.
Corporate strategy, on the other hand, is one that allows the company to generate elements that will increase its profit and strengthen its capacity to be more competitive. Examples of this type of strategy are the acquisition of subsidiary companies, the merger of competing companies and the restructuring of the company.

3. Assume that on January 2, 2022, the copyrighted item was impaired in its ability to continue to produce strong revenues. The other intangible assets were not affected. Starn estimated that the copyright would be able to produce future cash flows of $22,100. The fair value of the copyright was determined to be $21,100. Compute the amount, if any, of the impairment loss to be recorded.
Answer:
The amount of the impairment loss to be recorded is $6,800.
Explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
On January 1, 2020, Starn Tool & Manufacturing Company purchased a copyright for $31,000 cash. It is estimated that the copyrighted item will have no value by the end of 10 years.
Assume that on January 2, 2022, the copyrighted item was impaired in its ability to continue to produce strong revenues. The other intangible assets were not affected. Starn estimated that the copyright would be able to produce future cash flows of $22,100. The fair value of the copyright was determined to be $21,100. Compute the amount, if any, of the impairment loss to be recorded.
The explanation of the answer is now provided as follows:
Amortization expenses for 2020 = Annual amortization expense = Copyright cost / Estimated useful life of the copyright = $31,000 / 10 = $3,100
Book value of copyright on January 2, 2022 = Copyright cost - Amortization expenses for 2020 = $31,000 - $3,100 = $27,900
Copyright fair value = $21,100
Impairment loss = Book value of copyright on January 2, 2022 - Copyright fair value = $27,900 - $21,100 = $6,800
Therefore, the amount of the impairment loss to be recorded is $6,800.

Installing an automated production system costing $300,000 is initially expected to save Zia Corporation $52,000 in expenses annually. If the system needs $7,500 in operating and maintenance costs each year and has a salvage value of $30,000 at year 10, what is the IRR of this system
Answer:
8.87%
Explanation:
Internal rate of return is the discount rate that equates the after-tax cash flows from an investment to the amount invested
IRR can be calculated with a financial calculator
Cash flow in year 0 = $-300,000
Cash flow each year from year 1 to 9 = $52,000 - $7,500 = $44500
Cash flow in year 10 = $44500 + $30,000 = $74500
IRR = 8.87%
To determine the value of IRR using a financial calculator:
1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.
2. After inputting all the cash flows, press the IRR button and then press the compute button.

Assuming an income tax rate of 40% for all years, the affect of this accounting change on prior periods should be reported by a credit of:____________
Answer:
$450,000
Explanation:
Calculation to determine , the affect of this accounting change on prior periods that should be reported by a credit of:
Using this formula
Accounting change on prior periods=(2013 Percentage-of-Completion+2014 Percentage-of-Completion)-(2013 Completed-Contract+2014 Completed-Contract)*(1-Tax rate)
Let plug in the formula
Accounting change on prior periods=[($900,000+$950,000)-($475,000+$625,000)]*(1-40%)
Accounting change on prior periods=($1,850,000-$1,100,000)*0.60
Accounting change on prior periods=$750,000*.60
Accounting change on prior periods=$450,000
Therefore Assuming an income tax rate of 40% for all years, the affect of this accounting change on prior periods should be reported by a credit of:$450,000

Consumer surplus, is referred to as the economic measure of the excess benefit that a customer gets. The consumer surplus is the difference between the amount that the customer is willing to pay and the amount that he or she eventually pays.
Based on the question, the total Price paid is: 50 × $4 = $200
Total Revised Price = 50 × $5 = $250
Therefore, there will be a fall by $50 that's ($250 - $200).
Bush Company reported net income of $60,000 for the year. During the year, accounts receivable decreased by $8,000, accounts payable increased by $4,000 and depreciation expense of $5,000 was recorded. Net cash provided by operating activities for the year is Group of answer choices
Answer:
Net income from operating activities = $77000
Explanation:
Below is the calculation for Net income from operating activities:
Given the net income = $60000
Decrease in accounts receivable = $8000
Increase in accounts payable = $4000
Depreciation = $5000
Add the values in the net income in order to get the net income from operating activities.
Net income from operating activities = 60000 + 8000 + 4000 + 5000
Net Income from operating activities = $77000

If a coupon bond has two years to maturity, a coupon rate of 10 %, a par value of $1000 , and a yield to maturity of 12 %, then the coupon bond will sell for $nothing . (Round your response to the nearest two decimal place) The price of a bond and its yield to maturity are ▼ positively related negatively related unrelated .
Answer:
The right solution is "$966.27".
Explanation:
Given values are:
Coupon rate,
= 10%
Par value,
= $1000
Yield of maturity,
= 12%
then,
Coupon will be:
= [tex]1000\times 10 \ percent[/tex]
= [tex]1000\times 0.1[/tex]
= [tex]100[/tex] ($)
Now,
The present value of coupon will be:
= [tex]A\times \frac{(1-(1+r)^n)}{r}[/tex]
By putting the value, we get
= [tex]100\times \frac{1-(1.12)^{-2}}{0.12}[/tex]
= [tex]100\times \frac{1-0.7971}{0.12}[/tex]
= [tex]100\times \frac{0.2029}{0.12}[/tex]
= [tex]169.08[/tex] ($)
The present value of par value will be:
= [tex]\frac{1000}{(1+12 \ percent)^2}[/tex]
= [tex]\frac{1000}{(1.12)^2}[/tex]
= [tex]797.19[/tex] ($)
hence,
The price of bond will be:
= [tex]Present \ value \ of \ coupon+Present \ value \ of \ par \ value[/tex]
= [tex]169.08+797.19[/tex]
= [tex]966.27[/tex] ($)

Explanation:
A perfect competition is characterized by many buyers and sellers of homogenous goods and services. Market prices are set by the forces of demand and supply. There are no barriers to entry or exit of firms into the industry.
In the long run, firms earn zero economic profit. If in the short run firms are earning economic profit, in the long run firms would enter into the industry. This would drive economic profit to zero.
Also, if in the short run, firms are earning economic loss, in the long run, firms would exit the industry until economic profit falls to zero.
In 20X4, Bosh Corporation had income of $60,000 using absorption costing. Beginning and ending inventories were 13,000 and 8,000 units, respectively. The fixed manufacturing overhead cost was $4.00 per unit. What was the net income using direct/variable costing
Answer:
Net income under variable costing $80,000

The computation of the net income using direct/variable costing is shown below:
Net income under absorption costing $60,000
Add fixed cost under applied $20,000
Net income under variable costing $80,000
Working
Beginning inventory 13000
Less ending inventory -8000
Decrease in inventory 5000
Now under applied inventory $20,000
Danielle has loaned $500 to Richard at a 4% annual rate of interest for one year. If the inflation rate is constant at 7% for the entire term of the loan, how much purchasing power is lost after Richard repays the loan in full
Answer:
$15
Explanation:
In order to calculate the purchasing power lost the following formulae will be used:
Purchasing power lost = Loaned amount * (inflation rate - nominal rate)
Purchasing power lost = $500 * (0.07 - 0.04)
Purchasing power lost = $500 * 0.03
Purchasing power lost = $15
Hence, the purchasing power lost after Richard repays the loan in full is $15.
