We know that the sale price is $96 which is 80% (because 100% - 20% = 80%) of x, so we can write it down as: 96 = 80% from x 96 = 80/100 * x 96 = 8/10x 96 = 4/5x                      / * 5 (both sides) 480 = 4x                        / ÷ 4 (both sides) x = 120 Doublecheck: 120 * 80% = = 120 * 80/100 = = 120 * 4/5 = = 480/5 = = 96 So it's correct ;) Answer: The original price was $120.
