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

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
