Two stores sell the same refrigerator for the same original price. Store A advertises that the refrigerator is on sale for 15% off the original price. Store B advertises that it is reducing the refrigerator's price by $150. When Stephanie compares the sale prices of the refrigerator in both stores, she concludes that the sale prices are equal.

Let p represent the refrigerator's original price.

Which equation models this situation?

A. 0.85p = p - 150
B. 0.15p = p + 180
C. 0.15p = p - 150
0.85(p - 150) = p
