Question

two sporting goods stores are having discount sales on footballs. At one store, a basketball is on sale for 15% off the regular price of $22.95. At the other store, the same kind of basketball is on sale for 20% off the regular price of $24.75. What is the difference between the sale prices of the two stores?

Answer 1

Sale price for store A:
(100-15)/100×22.95
85/100×22.95
=$19.5075
~$19.5

Sale Price for store B:
(100-20)/100×24.75
80/100×24.75
=%$19.8
Thus the difference in the sale prices will be:
19.8-19.5
=$0.3
