Question

Ryan went to the store to buy some apples. The price per pound of the apples is $4.25

per pound and he has a coupon for $2 off the final amount. With the coupon, how much would Ryan have to pay to buy 5 pounds of apples? Also, write an expression for the cost to buy p pounds of apples, assuming at least one pound is purchased.

Answer 1

4.25*5 = 21.25; this is how much five pounds of apples will cost Ryan.

You have a $2 coupon off the final amount.
21.25 - 2 = $19.25

Therefore, it’ll cost Ryan $19.25 to buy 5 pounds of apples with his coupon.

The expression is $4.25 per pound.
So it is 4.25*p or 4.25p

Answer 2

see below

Explanation:

Cost for 5 pounds of apples:

($4.25 * 5 pounds) - $2 coupon

21.25 - 2

19.25

Cost of apples with p pounds: 4.25p

If one pound was purchase: 4.25p = 4.25(1) = 4.25
