Question

Amy paid ​$54.6654.66 for a pair of running shoes during a 1515​%-off sale. what was the regular​ price?

Answer 1

Let the regular price be x, then 15% of x, gives $54.66

i.e.

$\frac{(100-15)}{100} x=54.66 \\ \\ 0.85x=54.66 \\ \\ \Rightarrow x= \frac{54.66}{0.85} =\ 64.31$

Therefore, the regular price for the pairs of running shoes is $64.31
