Question

Khadija went to the store to buy some apples. The price per pound of the apples is $7.50 per pound and she has a coupon for $1.75 off the final amount. With the coupon, how much would Khadija have to pay to buy 4 pounds of apples? Also, write an expression for the cost to buy p p pounds of apples, assuming at least one pound is purchased.

Answer 1

Answer: 28.25$

Step-by-step explanation: To buy 4 pounds of apples, the cost would be 4 * $7.50 = $30.00.

The coupon would then reduce the total cost to $30.00 - $1.75 = $28.25.

For a general expression for the cost to buy p pounds of apples:

C = p * $7.50 - $1.75, where p >= 1.

This expression can be read as the cost (C) equals the number of pounds of apples (p) multiplied by the price per pound ($7.50), minus the coupon discount ($1.75).
