Question

Gabriela bought a new pair of sunglasses when they were having a 30% off sale if the regular price of the glasses was 72% how much did she pay with discount

Answer 1

Answer is: 50.4%. You have to take 30% off of 72%. Easiest way is to find 10% of 72 (7.2) and multiply that by 3 (=21.6). Then minus this off the original price (72 - 21.6 = 50.4)
