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.
0.25p = p – 180
0.75p = p + 180
0.25(p – 180) = p
0.75p = p − 180 **
