Tammy paid a total of $220 for a jacket, 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 4 times as much as the jacket. How much more did she pay for the pair of sport shoes than the jacket?
Amount that Tammy paid for the pair of socks
= ³₄ x 220 
= $165

Amount that Tammy left after buying the socks
= 220 - 165
= $55

Amount that Tammy paid for the jacket = 1 u
Amount that Tammy paid for the sport shoes = 4 u

Total amount spent on the jacket and the pair of sport shoes
= 1 u + 4 u
= 5 u

5 u = 55

1 u = 55 ÷ 5 = 11

Amount that Tammy paid more for the pair of sport shoes than the jacket
= 4 u - 1 u
= 3 u
= 3 x 11
= $33

Answer(s): $33
