Jaslyn paid a total of $162 for a jacket, a pair of socks and a pair of sport shoes. She spent ⁴₉ of her money on the pair of socks. The pair of sport shoes cost 9 times as much as the jacket. How much more did she pay for the pair of sport shoes than the jacket?
Amount that Jaslyn paid for the pair of socks
= ⁴₉ x 162 
= $72

Amount that Jaslyn left after buying the socks
= 162 - 72
= $90

Amount that Jaslyn paid for the jacket = 1 u
Amount that Jaslyn paid for the sport shoes = 9 u

Total amount spent on the jacket and the pair of sport shoes
= 1 u + 9 u
= 10 u

10 u = 90

1 u = 90 ÷ 10 = 9

Amount that Jaslyn paid more for the pair of sport shoes than the jacket
= 9 u - 1 u
= 8 u
= 8 x 9
= $72

Answer(s): $72
