Hello! So the original price is $120. It has a discount rate of 20%. You still pay 80% of the price, because 100 - 20 is 80. When we are looking for the sale price after the discount, we always mulitply the original amount by the percent of the price left to pay, after subtracting the discount from 100%. All we have to do is multiply 120 by 80% (0.8). 120 * 0.8 is 96. There. The sale price is $96. The answer is D: $96.
