Vanessa paid a total of $217 for a cardigan, a pair of socks and a pair of sport shoes. She spent ³₇ of her money on the pair of socks. The pair of sport shoes cost 3 times as much as the cardigan. How much more did she pay for the pair of sport shoes than the cardigan?
Amount that Vanessa paid for the pair of socks
= ³₇ x 217 
= $93

Amount that Vanessa left after buying the socks
= 217 - 93
= $124

Amount that Vanessa paid for the cardigan = 1 u
Amount that Vanessa paid for the sport shoes = 3 u

Total amount spent on the cardigan and the pair of sport shoes
= 1 u + 3 u
= 4 u

4 u = 124

1 u = 124 ÷ 4 = 31

Amount that Vanessa paid more for the pair of sport shoes than the cardigan
= 3 u - 1 u
= 2 u
= 2 x 31
= $62

Answer(s): $62
