Percentage reduction = (Original price - Reduced price) / Original price * 100
In this case, the original price of the jacket is $20 and the reduced price is $14. Plugging these values into the formula, we get:
Percentage reduction = (20 - 14) / 20 * 100
Percentage reduction = 6 / 20 * 100
Percentage reduction = 0.3 * 100
Percentage reduction = 30%
Therefore, the correct answer is D) 30%.

For last week:
Monday class: 3 hours
Friday class: 1 hour
Total hours: 3 + 1 = 4 hours
For this week:
Monday class: 3 hours
Friday class: 1 hour
Total hours: 3 + 1 = 4 hours
To find the total hours for both weeks, we add the totals together:
4 hours + 4 hours = 8 hours
Therefore, the correct answer is C) 8 hours.

Distance from school to the ice cream shop: 11 miles
Distance from the ice cream shop to her house: 2/3 of a mile
To add the distances together, we need to find a common denominator for the fractions. In this case, the lowest common denominator is 3.
Converting the fraction 2/3 to have a denominator of 3, we get: (2/3) * (3/3) = 6/9
Adding the distances together:
11 miles + 6/9 miles = 99/9 miles + 6/9 miles = 105/9 miles
Simplifying the fraction, we get:
105/9 miles = 11 6/9 miles
Therefore, the correct answer is B) 11 6/9 miles.
2 3the ice cream shop to her house. How many miles did Marissa walk in all?
Responses
A 1 3/5
B 5/6
C -5/6
D 2 1/6
Distance from school to the ice cream shop: 1 1/2 miles (or 3/2 miles)
Distance from the ice cream shop to her house: 2/3 of a mile
To add the distances together, we need to find a common denominator for the fractions. In this case, the lowest common denominator is 6.
Converting the mixed number 1 1/2 to an improper fraction with a denominator of 6, we get:
1 1/2 = (6/6) + (3/6) = 9/6 + 3/6 = 12/6
Adding the distances together:
12/6 miles + 2/3 miles = (12/6) + (4/6) = 16/6 miles
Simplifying the fraction, we get:
16/6 miles = 2 2/6 miles = 2 1/3 miles
Therefore, the correct answer is not listed among the given responses.
5cover her room. The price for carpet is $4.50 per square foot. How much will it cost Felicity to purchase carpet for her bedroom?
Responses
A $588.60$588.60
B $29.07$29.07
C $135.30$135.30
D $126.30
Area of the room: 130 4/5 square feet (or 130.8 square feet)
Price per square foot: $4.50
To find the total cost, we multiply the area by the price:
130.8 square feet * $4.50/square foot = $588.60
Therefore, the correct answer is A) $588.60.
Responses
A $538.74$538.74
B $120,000$120,000
C $1,200.00$1,200.00
D $5,387.42
A = P(1 + r/n)^(nt)
Where:
A = final amount
P = principal amount (initial deposit)
r = annual interest rate (as a decimal)
n = number of times interest is compounded per year
t = number of years
In this case:
P = $4,000
r = 6% = 0.06 (as a decimal)
n = 4 (compounded quarterly)
t = 5 years
Plugging these values into the formula:
A = $4,000(1 + 0.06/4)^(4*5)
A = $4,000(1 + 0.015)^20
A = $4,000(1.015)^20
A ≈ $4,000(1.3444991)
A ≈ $5,377.9964
Therefore, the correct answer is D) $5,387.42 (rounded to the nearest cent).
Discount 1: Take 10% off the original price of a car built last year and then receive a $2,500 rebate.
Discount 2: Take 15% off the original price of a car built this year and then receive a $1,500 rebate.
A customer is deciding between two cars.
Car A was built last year and has a price of $26,750.
Car B was built this year and has an original price of $24,012.
Based on this information, which statement is true?
Responses
A The customer would pay $21,000 for Car A.The customer would pay $21,000 for Car A.
B The customer would pay $18,250 for Car B.The customer would pay $18,250 for Car B.
C The customer would pay $21,575 for Car A.The customer would pay $21,575 for Car A.
D The customer would pay $18,645 for Car B. The customer would pay $18,645 for Car B.
For Car A:
Discount 1: 10% off the original price of $26,750
= $26,750 * 0.10
= $2,675
After applying the rebate of $2,500:
Final price for Car A = Original price - Discount 1 - Rebate
= $26,750 - $2,675 - $2,500
= $21,575
For Car B:
Discount 2: 15% off the original price of $24,012
= $24,012 * 0.15
= $3,601.80
After applying the rebate of $1,500:
Final price for Car B = Original price - Discount 2 - Rebate
= $24,012 - $3,601.80 - $1,500
= $18,910.20
Therefore, the correct statement is:
C) The customer would pay $21,575 for Car A and $18,910.20 for Car B.

D 45
In this case, we have the following angles:
(2x + 13)
75
(67 - x)
To find the value of x, we can set up the equation:
(2x + 13) + 75 + (67 - x) = 180
Combining like terms:
2x + 75 + 67 - x = 180
x + 142 = 180
x = 180 - 142
x = 38
Therefore, the correct answer is not listed among the given responses.
