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.
Which equation models this situation?

0.25p=p−180

0.75p=p−180

0.75p=p+180

0.25(p−180)=p
