Question

To get more restful sleep, Rosa bought a new memory foam mattress from Rest Masters. She used a $75.00 gift card for part of her purchase. Then, Rosa charged the remaining $210.60 to her credit card.
Let p represent the original purchase amount. Which equation models the problem?
Solve this equation to find the original purchase amount.

Answer 1

Let p be the original price. After using a $75 gift card, the remainder charged was $210.60, so

p − 75 = 210.60.

Solve: p = 210.60 + 75 = 285.60.

The original purchase amount was $285.60.
