Question

Amelia purchased a new mattress when it was on sale. The sale price was 25% less than the regular price. If the sale price was $481, what was the original price? (Round your answer to the nearest dollar).

Answer 1

$641

Explanation:

Let $p be the original price.

`(1 - 25\%)p = 481 \\ (75)/(100) p = 481 \\ p = 641`

p = 641 (cor. to the nearest dollar)

∴ The original price was $641.
