Question

Mariana went to the store to buy some chicken. The price per pound of the chicken is $6.25 per pound and she has a coupon for $3.25 off the final amount. With the coupon, how much would Mariana have to pay to buy 5 pounds of chicken? Also, write an expression for the cost to buy

�
p pounds of chicken, assuming at least one pound is purchased.

Answer 1

Answer: Without the coupon, Mariana would have to pay $6.25 per pound of chicken, so for 5 pounds, the cost would be:

5 * $6.25 = $31.25

With the coupon, she would receive a discount of $3.25, so the final cost would be:

$31.25 - $3.25 = $28.00

To write an expression for the cost to buy p pounds of chicken, we can use the formula:

C = 6.25p - 3.25

where C is the cost in dollars and p is the number of pounds of chicken purchased. Note that the expression assumes that at least one pound is purchased, as indicated in the question.
