Answers

Answer 1

Answer:

$25,000

Explanation:

The computation of the estimated total fixed cost is shown below:

But before that the variable cost per unit is

= ($61,000 - $31,000) ÷ (2,400 - 400)

= $30,000 ÷ 2,000

= $15

Now the estimated fixed cost is

= $61,000 - $15 × 2,400

= $61,000 - $36,000

= $25,000

Answers

Answer:

$1,000,000

Explanation:

The full question is shown below:

You would like to have enough money saved to receive $80,000 per year in perpetuity after retirement for you and your heirs. How much would you need to have saved in your retirement fund to achieve this goal? (Assume that the perpetuity payments start one year from the date of your retirement. The annual interest rate is 8 percent.)

In order to receive $80,000 per year forever, one needs to save the present value of the annual  cash flow using the present value formula for perpetuity as provided below:

PV of perpetuity=annual cash flow/annual interest rate

PV of perpetuity=$80,000/8%

PV of perpetuity=$1,000,000

A project is expected to generate annual revenues of $132,100, with variable costs of $80,200, and fixed costs of $20,700. The annual depreciation is $4,750 and the tax rate is 35 percent. What is the annual operating cash flow

Answers

Answer:

$21,943

Explanation:

Calculation to determine the annual operating cash flow

Using this formula

Operating Cash Flow =(Annual Revenue-Variable costs - Fixed costs)×(1-Tax rate)+( Annual depreciation×Tax rate )

Let plug in the formula

Operating Cash Flow =[ ($132,100 - $80,200 - $20,700) x (1 - 0.35)]+ ($4,750 x 0.35)

Operating Cash Flow =

Operating Cash Flow =($31,200×0.65)+$1,663

Operating Cash Flow =$20,280+$1,663

Operating Cash Flow =$21,943

Therefore the annual operating cash flow is $21,943

When the selling division in an internal transfer has unsatisfied demand from outside customers for the product that is being transferred, then the lowest acceptable transfer price as far as the selling division is concerned is:

Answers

Answer: c. the market price charged to outside customers

Explanation:

When a division is able to sell its products to customers outside the company for a certain price but instead has to transfer these to another division in the company, the minimum transfer price will have to be the selling price to the customers outside so that the division would not make losses.

The division that this good is transferred to will then reflect the cost of acquiring the goods as that selling price. This cost will be accounted for when the new division wants to sell their own goods that way this cost will be recuperated on a company level.

A company borrowed $10,000 from the bank at 5% interest. The loan has been outstanding for 45 days. Demonstrate the required adjusting entry for this company by completing the following sentence. The required adjusting entry would be to debit the Interest __________________ account and ___________________ the Interest ___________________ account.

Answers

Answer:

The required adjusting entry would be to debit the Interest expense account and credit the Interest payable account.

Explanation:

The number of days that a loan debt stays unpaid is referred to as the outstanding number of days.

In line with the general accounting rules, all expenses must be debited. Therefore, the interest expense has to be debited.

Interest payable, however, is the amount owed to a lender by a firm and is thus credited as the matching journal entry to the interest expense.

Therefore, we have:

The required adjusting entry would be to debit the Interest expense account and credit the Interest payable account.

Answers

Answer:

$3,083,333.33

Explanation:

Weighted average accumulated expenditures = ($2,500,000*6/12) + ($5,500,000*4/12)

Weighted average accumulated expenditures = $1,250,000 + $1,833,333.33

Weighted average accumulated expenditures = $3,083,333.33

So, the amount of weighted average accumulated expenditures is $3,083,333.33.

A company purchased a computer system at a cost of $26,000. The estimated useful life is 8 years, and the estimated residual value is $4,000. Assuming the company uses the double-declining-balance method, what is the depreciation expense for the second year

Answers

Answer:

the depreciation expense for the second year is $4,875

Explanation:

The calculation of the depreciation expense for the second year is given below:

First the depreciation rate should be

= 1 ÷ 8 × 2

= 25%

Now the first year depreciation is

= $26,000 × 25%

= $6,500

Now the second year depreciation should be

= ($26,000 - $6,500) × 2

= $4,875

Hence, the depreciation expense for the second year is $4,875

Answers

Answer:

$24.7

Explanation:

The first step is to calculate D1

1.65(1+5/100)

1.65(1+0.05)

1.65(1.05)

=>1.73

Therefore the current price can be calculated as follows

= 1.73/0.12-0.05

= 1.73/0.07

= 24.7

Hence the current price is $24.7

A company has already incurred $7,200 of costs in producing 6,000 units of Product XY. Product XY can be sold as is for $31 per unit. Instead, the company could incur further processing costs of $10 per unit and sell the resulting product for $35 per unit. Should the company sell Product XY as is or process it further

Answers

Answer: Sell as is or lose $36,000

Explanation:

If the company sells as is, they could sell at a price of $31 per unit.

If they process further and sell at $35, they would incur a cost of $10 per unit which leaves them with profit of:

= 35 - 10

= $25

This is lower than the selling price if they sell as is and will therefore give a loss of:

= (31 - 25) * 6,000 units

=- $36,000

Company should sell as is so as not to lose $36,000

You have $100,000 to invest in a portfolio containing Stock X and Stock Y. Your goal is to create a portfolio that has an expected return of 12.1 percent. Stock X has an expected return of 10.28 percent and a beta of 1.20, and Stock Y has an expected return of 7.52 percent and a beta of .80.
a. How much money will you invest in Stock Y? (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
b. What is the beta of your portfolio? (Do not round intermediate calculations and round your answer to 3 decimal places, e.g., 32.161.)
a. Investment in Stock Y
b. Portfolio beta

Answers

Answer:

a. Amount to invest in Y

The amount that will be invested in Stock Y should be such that the expected return of the portfolio would equal 12.1%.

This would be determined by the weights of the stock.

Assume the weight to be invested in X is x.

Portfolio return = (weight of X * Return of X) + (weight of Y * Return of Y)

12.1% = (x * 10.28%) + ( (1 - x) * 7.52%)

0.121 = 0.1028x + 0.0752 - 0.0752x

0.121 - 0.0752 = 0.1028x - 0.0752x

0.0458 = 0.0276x

x = 0.0458 / 0.0276

= 1.6594

Weight in stock Y:

= 1 - 1.6594

= -0.6594

Amount to invest in Y:

= -0.6594 * 100,000

= -$65,940

b. Portfolio beta

It will be a weighted average of the betas of the two stocks:

= (Weight of stock X * Stock X Beta) + ( Weight of stock Y * Stock Y beta)

= (1.6594 * 1.20) + (-0.6594 * 0.80)

= 1.46

a. store manager salaries
b. store building depreciation expense
c. the cost of corporate advertising aired during the Super Bowl
d. cost of goods sold at each store
e. none of the above

Answers

Answer: c. the cost of corporate advertising aired during the Super Bowl

Bonita Industries uses flexible budgets. At normal capacity of 21000 units, budgeted manufacturing overhead is $168000 variable and $360000 fixed. If Bonita had actual overhead costs of $546000 for 26000 units produced, what is the difference between actual and budgeted costs

Answers

Answer:

$22,000 Favorable

Explanation:

The computation of the difference between actual and budgeted cost is given below:

Budgeted Variable Manufacturing Overhead Per Unit is

= $168,000 ÷ 21,000 units

= $8

The Fixed Overhead = $360,000

Now

For 26,000 Units, total Overhead Should be:

Variable = 26,000 × 8 = $208,000

Fixed = $360,000

Total = $568,000

And,  

Actual Overhead Cost = $546,000

So,  

Difference between Actual and Budgeted Cost is

= $568,000 - $546,000

= $22,000 Favorable
