To find the original price of the shoes, you can use the given information that the selling price ($150) is 85% of the original price.
Let \(P\) be the original price. According to the problem, 85% of \(P\) is equal to $150:
\[0.85P = 150\]
To find \(P\), divide both sides of the equation by 0.85:
\[P = \frac{150}{0.85}\]
\[P \approx 176.47\]
The original price of the shoes was approximately $176.47.
