You have $100 in your bank account. After the first year, you have $107 in your bank account. Calculate the percent increase.
- A.
0.067%
- B.
0.07%
- C.
6.5%
- D.
7%
Correct Answer
D. 7%Explanation
The percent increase can be calculated by finding the difference between the final amount and the initial amount, dividing it by the initial amount, and then multiplying by 100. In this case, the difference is $7 ($107 - $100), and the initial amount is $100. Dividing $7 by $100 gives 0.07, and multiplying by 100 gives 7%. Therefore, the percent increase is 7%.Rate this question:

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?
- A.
20%
- B.
25%
- C.
30%
- D.
35%
Correct Answer
A. 20%Explanation
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.Rate this question:

Each week, Ainsley spends $28 at the local coffee shop. If she gets a total of $50 each week from her parents for her allowances, what percentage of her allowance is she spending at the coffee shop each week?
- A.
56%
- B.

- C.
22%
- D.
28%
Correct Answer
A. 56%Explanation
Ainsley spends $28 at the local coffee shop each week. Her total allowance is $50 each week. To find the percentage of her allowance she spends at the coffee shop, we divide the amount she spends ($28) by her total allowance ($50) and multiply by 100. This gives us (28/50) * 100 = 56%. Therefore, 56% of her allowance is spent at the coffee shop each week.Rate this question:

Dashawn bought a CD that cost $18.99 and paid $20.51, including tax. What was the percent of tax he paid?
- A.
5%
- B.
2%
- C.
3%
- D.
8%
Correct Answer
D. 8%Explanation
Dashawn paid $20.51 in total, which includes the cost of the CD and the tax. To find the percent of tax he paid, we need to calculate the difference between the total amount paid and the cost of the CD. The difference is $20.51 - $18.99 = $1.52. To find the percent, we divide this difference by the cost of the CD and multiply by 100: ($1.52 / $18.99) * 100 = 8%. Therefore, Dashawn paid 8% in tax.Rate this question:

Ms. Ward wants to buy a suit marked $60. She receives a 25% discount, and then there is a 7% sales tax. How much does Ms. Ward actually spend on the suit?
- A.
$45
- B.
$15
- C.
$48.15
- D.
$69.75
Correct Answer
C. $48.15Explanation
After receiving a 25% discount, Ms. Ward would be paying 75% of the original price. So, the amount she spends on the suit after the discount is 0.75 * $60 = $45. Then, there is a 7% sales tax added to this amount. The sales tax is calculated as 7% of $45, which is 0.07 * $45 = $3.15. Adding this sales tax to the discounted price, Ms. Ward actually spends $45 + $3.15 = $48.15 on the suit.Rate this question:

Carmen scored 18 question correct on a test. IF she received a 72% on the test, how many questions were on the test?
- A.
20
- B.
120
- C.
50
- D.
25
Correct Answer
D. 25Explanation
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. We can write the proportion as 18/x = 72/100, where x represents the total number of questions. Cross multiplying gives us 18 * 100 = 72 * x, which simplifies to 1800 = 72x. Dividing both sides by 72 gives us x = 25. Therefore, there were 25 questions on the test.Rate this question:

A video game originally priced at $65.50 is on sale at 12% discount. What is the sale price?
- A.
$7.86
- B.
$73.86
- C.
$57.64
- D.
$65.38
Correct Answer
C. $57.64Explanation
The original price of the video game is $65.50. It is on sale at a 12% discount. To find the sale price, we need to subtract 12% of $65.50 from the original price. 12% of $65.50 is $7.86. Subtracting $7.86 from $65.50 gives us $57.64, which is the sale price of the video game.Rate this question:
