amy paid 55.42 for a pair of running shoes during a 15%-off sale. What was the regular price?

55.42/0.85 = original price = ___

To find the regular price of the running shoes, we need to use the information given.

We know that Amy paid $55.42 for the shoes after a 15% discount was applied.

First, let's calculate what 15% of the regular price is:
15% of the regular price = (15/100) * regular price

Now, we can set up an equation to find the regular price:
Regular price - 15% of regular price = $55.42

Simplifying the equation:
Regular price - 0.15 * Regular price = $55.42

Combining like terms:
0.85 * Regular price = $55.42

Now, to calculate the regular price, divide both sides of the equation by 0.85:
Regular price = $55.42 / 0.85

Calculating the regular price:
Regular price ≈ $65.20

So, the regular price of the running shoes was approximately $65.20.
