Question

Amy paid 92.82 for a pair of running shoes during a 25% off sale. What was the regular price?

Answer 1

You know $89.64 is 65% 
and you want to find out 100% 

so: 

??? = 100% 
89.64 = 65% 

89.64 x 100 = 8964 
8964 : 65 = 137.90769 

So you know 100% are 137.90769 

Then you round up to 2 decimals 

So the answer is, before the sale the shoes cost $137.91
