Olivia pays $189 for a painting, including tax.
If the actual price is $179.50, what is the sales tax rate?
Answers
1. you would take 189 and subtract 179.50
2. from that you would get 9.50
3. you would then divide 9.50 by 179.50
4. therefore the tax rate would be 0.05 or 5%
The sales tax rate = 5.29%
What is the formula for tax rate?"Tax rate = (Tax amount / Price before tax) × 100% "
What is the formula for tax amount?"Tax amount = Final price - Price before tax"
For given question,
Olivia pays $189 for a painting, including tax.
⇒ Final price = $189
The actual price of the painting is $179.50
⇒ Price before tax = $179.50
Using the formula of tax amount,
⇒ Tax amount = Final price - Price before tax
⇒ Tax amount = 189 - 179.50
⇒ Tax amount = 9.5
Now we find the sales tax rate.
Using the formula of tax rate,
⇒ Tax rate = (Tax amount ÷ Price before tax) × 100%
⇒ Tax rate = [tex]\frac{9.5}{179.50} \times 100~\%[/tex]
⇒ Tax rate = 5.29%
Therefore, the sales tax rate = 5.29%

A 1400-seat theater sells two types of tickets for a concert. Premium seats sell for $30 each and regular seats sell for $20 each. At one event $33,950 was collected in ticket sales with 10 seats left unsold. How many of each type of ticket was sold?
Answers
Answer:
x = 638
y = 1190 - 638 = 552
Step-by-step explanation:
Let x = premium seats
let y = regular seats
x + y = 1190 (ten were not sold
30x + 20y = 30180 (amount collected
now multiply the first equation by 20 and subtract
20x + 20y = 23800
30x + 20y = 30180
-10x = -6380
x = 638
y = 1190 - 638 = 552
check it by multipying x and y by their price to see if you come up with the correct amount
Hope this helps
Regular seats sold: 552

First we have to take any point, I'll take (5,3).
X-axis represents number of pounds and y-axis represents total cost (in $).
So, 5 pounds = $3
=> 1 pound = $3/5
=> 1 pound = $0.6
=> 1 pound = 60 cents

60c per pound.

what is the gradient?
Answers
Answer:
[tex]{ \tt{gradient = \frac{ - 3 - 1}{0 - ( - 1)} }} \\ = \frac{ - 4}{1} \\ = - 4[/tex]
Answer:
The gradient (slope) is -4.
Step-by-step explanation:
Note that two points on the graph through which the blue line passes exactly are (-2, 5) and (0, -3). As we move from the first point to the second, x increases by 2 (the 'run') and y (the 'rise') decreases by 8. Thus, the gradient, or slope, of this line is m = rise/run = -8/2, or m = -4.
MacKenzie surveys 80 of her classmates and finds that 65% of them like sports. She also finds that 75% of her 64 relatives like sports. How many more of her classmates like sports as compared to her relatives? Pls help
Answers
Answer:
65%×80=52
(80-52=28) no of classmates who liked sports
75%×64=48
(64-48=16) no of relatives who liked sports
no of classmates who liked sports - no of relatives who liked sports
= 28-16 = 12
Hence, 12 more of her classmates like sports as compared to her relatives
There are total 4 more of her classmates like sports as compared to her relatives.
What is the Percentage?The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.
As per the information given in the question,
Total number of students surveyed = 80
Percentage of students who like sports = 75%
So,
(80 × 65)/100
= 5200/100 = 52
Total number of Relatives = 64
Percentage of relatives who like sports = 75%
So,
(64 × 75)/100
= 4800/100 = 48
Then, the number more of her classmates like sports compared to relatives will be:
52 - 48
= 4

Johnny rode his bicycle down a hill. It took him 15 seconds to ride from the top of the hill to the bottom of the hill. The equation h = -3t + 45 models his height, h, in feet, above the bottom of the hill as a function of the time, t, in seconds, after he started riding down the hill. Part A: What is the average rate of change in Johnny’s height? Part B: What is the height of the hill? Part C: How long will it take Johnny to travel 1/3 of the distance down the hill?
Answers
From the height function, we get that:
a) The average rate of change is of -3 feet per second.
b) The height of the hill is of 45 feet.
c) It will take Johnny 5 seconds to travel 1/3 of the distance down the hill.
-------------------------------
The height, after t seconds, is given by:
[tex]h(t) = -3t + 45[/tex]
-------------------------------
The height of the hill is [tex]h(t)[/tex] when [tex]t = 0[/tex], thus [tex]h(0) = -3(0) + 45 = 45[/tex]. 45 feet, which means that the the answer for option B is 45 feet.-------------------------------
Item a:
The initial height is of 45 feet, at [tex]t = 0[/tex] seconds.The final height is of 0 feet, at [tex]t = 15[/tex] seconds.Thus, the average rate of change is given by:[tex]A = \frac{0 - 45}{15 - 0} = -\frac{45}{15} = -3[/tex]
The average rate of change is of -3 feet per second.
-------------------------------
Item c:
One-third of the distance of 45 feet is [tex]\frac{1}{3}45 = 15[/tex] feet, thus, we have to find the time at which he is at 30 feet, that is, t for which [tex]h(t) = 30[/tex][tex]h(t) = -3t + 45[/tex]
[tex]30 = -3t + 45[/tex]
[tex]3t = 15[/tex]
[tex]t = \frac{15}{3}[/tex]
[tex]t = 5[/tex]
It will take Johnny 5 seconds to travel 1/3 of the distance down the hill.

Find the sum of the counting numbers from 1 to 25 inclusive. In other words, if S = 1 + 2 + 3 + ... + 24 + 25, find the value of S.
Answers
Answer:
325
Step-by-step explanation:
You must have heard about Arithmetic Progressions (AP)
Arithmetic progressions are a series of numbers such that every successive number is the sum of a constant number and the previous number.
Our very own counting numbers form AP
For example :-
2 = 1 + 1
3 = 2 + 1
4 = 3 + 1
The number in bold (1) is that constant number which is added to a number to form its successive number.
To find the sum of series forming AP, we use the formula :-
[tex]sum = \frac{n}{2} \{ a + a _{n} \} [/tex]
here,
n is the number of termsa is the first number of the series an is the last number of the seriesSo we'll use all this information to find the sum of continuous numbers from 1 to 25 where 1 is the first term(a) and 25 is the last(an).
and n is 25
[tex]S = \frac{25}{2}\{ 1 +25\} [/tex]
[tex] = \frac{25 \times 26}{2} [/tex]
[tex] = 25 \times 13[/tex]
[tex] = 325[/tex]
So, the value of S comes out to be 325.
Answer:
s= 325
Step by step explanation:
Add all numbers 1 to 25 to get 325.

Elliot has been running a lawn care business since 2000. He cuts grass, trims, and weed whacks yards for his customers throughout the season. Each year, he has increased his fee by the same amount. The table shows what Elliot charged each customer for two given years of his business:
Year Lawn Care Fee
2000 $750
2010 $1350
A. What is the rate of change and initial value for Elliot’s business? How do you know?
B. Write an equation in slope-intercept form to represent the fees that Elliot charges each year.
Answers
2010-2000=10 years
600/10=$60 increase per year
a) since elliot started with $750 in 2000 and he started working in 2000 that would be his initial fee and every year he increased his fee by $60.
b) y=60x+750
Answer:
Rate of Change: $60 Per year
Step-by-step explanation:
We can find how many years are from 2000 to 2010 not overcouting. That is 10. Now, we do 1350 minus 750 because that's the change of the fee. That will give you 600. Now, 600 divided by 10, giving you how much change each year. That's 60.
So,
2000:750
2001:810
2002:870
2003:930
2004:990
2005:1050
2006:1110
2007:1170
2008:1230
2009:1290
2010: 1350
You can graph it out with that, now.
