Tiffany paid a total of $180 for a sweater, a pair of socks and a pair of sneakers. She spent ³₄ of her money on the pair of socks. The pair of sneakers cost 4 times as much as the sweater. How much more did she pay for the pair of sneakers than the sweater?
Amount that Tiffany paid for the pair of socks
= ³₄ x 180 
= $135

Amount that Tiffany left after buying the socks
= 180 - 135
= $45

Amount that Tiffany paid for the sweater = 1 u
Amount that Tiffany paid for the sneakers = 4 u

Total amount spent on the sweater and the pair of sneakers
= 1 u + 4 u
= 5 u

5 u = 45

1 u = 45 ÷ 5 = 9

Amount that Tiffany paid more for the pair of sneakers than the sweater
= 4 u - 1 u
= 3 u
= 3 x 9
= $27

Answer(s): $27
