Amy paid $72.25 for a pair of running shoes during a 15%-off sale. What was the regular price?

Step 1. Percentage of 15% means 0.15.

Step 2. Let x be the regular price of the running shoes.

Step 3. Let 0.15x be the amount off the regular price due to the sales of 15%.

Step 4. Let x-0.15x be the sales price.

Step 5. Then x-0.15x=72.25 or 0.85x=72.25.

Divide by 0.85 to both sides to get the sales price.


0.85x%2F0.85=72.25%2F0.85

x=85

Step 6. ANSWER: The regular price is $85.00.

I hope the above steps and explanation were helpful.
