Question

This is my sister's 7th grade work. Can anyone help?
Derek’s favorite clothing store is having their annual fall sale. All clothing is 25 percent off. A shirt he really likes has an original price of $28. Derek has $24 in his wallet. He is wondering if he has enough money to buy the shirt now that it is on sale. He knows he must also pay sales tax. The sales tax rate is 8 percent and is calculated on the discounted price. Does Derek have enough money to buy the shirt? Justify your answer. Your explanation should contain answers to the following questions:

Answer 1

1. What is the amount of the discount?

2. What is the sale price?

3. How much will Derek pay in sales tax?

4. What is the total cost of the shirt?

5. Does Derek have enough money to buy the shirt?

Answer 2

original price is $ 28

amount of discount is 0.25(28) =
sale price is : 28 - 0.25(28) =
do these first....and then we will continue

Answer 3

sales tax would be : 0.08 x sales price (the answer you got for the second one)

Answer 4

Amount of discount is 7
Sales Price is 21
sales tax is 1.68

Answer 8
