Winnie paid a total of $168 for a hoodie, a pair of socks and a pair of ballet shoes. She spent ²₃ of her money on the pair of socks. The pair of ballet shoes cost 6 times as much as the hoodie. How much more did she pay for the pair of ballet shoes than the hoodie?
Amount that Winnie paid for the pair of socks
= ²₃ x 168 
= $112

Amount that Winnie left after buying the socks
= 168 - 112
= $56

Amount that Winnie paid for the hoodie = 1 u
Amount that Winnie paid for the ballet shoes = 6 u

Total amount spent on the hoodie and the pair of ballet shoes
= 1 u + 6 u
= 7 u

7 u = 56

1 u = 56 ÷ 7 = 8

Amount that Winnie paid more for the pair of ballet shoes than the hoodie
= 6 u - 1 u
= 5 u
= 5 x 8
= $40

Answer(s): $40
