Winnie paid a total of $180 for a sweater, a pair of socks and a pair of sport shoes. She spent ³₄ of her money on the pair of socks. The pair of sport shoes cost 8 times as much as the sweater. How much more did she pay for the pair of sport shoes than the sweater?
Amount that Winnie paid for the pair of socks
= ³₄ x 180 
= $135

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

Amount that Winnie paid for the sweater = 1 u
Amount that Winnie paid for the sport shoes = 8 u

Total amount spent on the sweater and the pair of sport shoes
= 1 u + 8 u
= 9 u

9 u = 45

1 u = 45 ÷ 9 = 5

Amount that Winnie paid more for the pair of sport shoes than the sweater
= 8 u - 1 u
= 7 u
= 7 x 5
= $35

Answer(s): $35
