Two stores sell the same computer for the same original price. Store A advertises that the computer is on sale for 25% off the original price. Store B advertises that it is reducing the computer’s price by $180. When Brittany compares the sale prices of the computer in both stores, she concludes that the sale prices are equal.
Let p represent the computer’s original price.
What equation models this situation?
A. 0.75p=p+1800.75p=p+180
B. 0.25(p−180)=p0.25(p−180)=p
C. 0.25p=p−1800.25p=p−180
D. 0.75p=p−180
