Question

You have a coupon for an additional 25% off the price of any sale item at a store. The store has put a watercolor kit on sale for 15% off the original price of $40. What is the price of the watercolor kit after both discounts?

Answer 1

final price=original price*(100%- discount 1)(100%-discount 2) 
original price=$40
discount 1=25%⇒         100 - discount 1=100%-25%=75%=75/100=0.75
discount 2=15%⇒         100 - discount 2=100%-12%=85%=85/100=0.85

original price=$40(0.75)(0.85)=$25.5


Answer: $25.5
