Question

Sweaters already on sale for 20% off the regular price cost $36 when purchased with a promotional coupon that allows an additional 10% discount. What is the original price?

Answer 1

36/9(because 36 is 90%)=4, 4*10=$40
40/8(because 40 is 80%)=5, 5*10=$50

50*.8(to find 80%)=40
40*.9(to find 90%)=36

Answer: The original price was $50
