What was the regular price?

Question

Amy paid $54.72 for a pair of shoes during a sale that was 40%-off. What was the regular price of the shoes?

Answer 1

Since the shoes were 40% off, $54.72 is 100%-40%=60% of the original price.

$54.72=60%*R=0.6*R where R = regular price

Then, R=54.72/0.6 = $91.20.
