The regular price of a pair of shoes is $48. The store is having a buy one get one 1/2 off sale. If you buy 2 pairs of shoes for that price, what percent discount is that?
First pair =$48
Second pair =$48/2 =$24
$48 + $24 =$72 - The cost of 2 pairs of shoes after discount.
$48 x 2 =$96 - The cost of 2 pairs of shoes without discount.
1 - (72/96) x 100 =25% - The overall discount on total sale of 2 pairs of shoes.
