$7.86

$73.86

$57.64

Ms. Ward wants to buy a suit marked at $60. She receives a 25% discount, which means she will pay only 75% of the original price. Therefore, she will pay 0.75 * $60 = $45. After that, there is a 7% sales tax, which is calculated by multiplying the price by 0.07. Therefore, the amount Ms. Ward actually spends on the suit is $45 + ($45 * 0.07) = $48.15.

7) AJ purchased a new tv for $1200. The regular price of the tv was $1500. What percent did AJ save by buying it on sale?

20%

25%

30%

35%

AJ saved 20% by buying the TV on sale. To calculate the percentage saved, we can use the formula: (Regular price - Sale price) / Regular price * 100. In this case, the regular price was $1500 and the sale price was $1200. Plugging these values into the formula, we get (1500 - 1200) / 1500 * 100 = 300 / 1500 * 100 = 0.2 * 100 = 20%. Therefore, AJ saved 20% by buying the TV on sale.

8) Carmen scored 18 question correct on a test. IF she received a 72% on the test, how many questions were on the test?

20

120

50

25

If Carmen scored 18 questions correct on a test and received a 72% on the test, we can set up a proportion to find the total number of questions on the test. The proportion can be set up as 18/x = 72/100, where x represents the total number of questions. Cross multiplying, we get 18 * 100 = 72 * x, which simplifies to 1800 = 72x. Dividing both sides by 72, we find that x = 25. Therefore, there were 25 questions on the test.

9) Dashawn bought a CD that cost $18.99 and paid $20.51, including tax. What was the percent of tax he paid?

5%

2%

3%

8%

Dashawn paid $20.51 for the CD, which includes the cost of the CD and the tax.

10) The apple store charges a 2.9% shipping and handling fee for online payments. How much would you pay total if you spent $1,500?

$1065

$43.50

$1543.50

$146.50

If the apple store charges a 2.9% shipping and handling fee for online payments, it means that for every $100 spent, $2.90 would be added as a fee. Therefore, for a $1,500 purchase, the fee would be 2.9% of $1,500, which is $43.50. Adding this fee to the original purchase amount, the total amount to be paid would be $1,500 + $43.50 = $1543.50.
