The normal cost of a basketball is $21.50. We purchased the basketball for Mason using a coupon for 25% off. How much did we pay for the basketball? $13.65 $18.25 $16.13

First find 25% of 21.5. You can do this by multiplying. 25 by 21.5. That gives you 5.375. Subtract that from 21.5. That gives you 16.125. Money only has two decimal places so round 16.125 up to 16.13 and that's your answer! <3
