Ivory paid a total of $245 for a jacket, a pair of socks and a pair of flippers. She spent ³₇ of her money on the pair of socks. The pair of flippers cost 9 times as much as the jacket. How much more did she pay for the pair of flippers than the jacket?
Amount that Ivory paid for the pair of socks
= ³₇ x 245 
= $105

Amount that Ivory left after buying the socks
= 245 - 105
= $140

Amount that Ivory paid for the jacket = 1 u
Amount that Ivory paid for the flippers = 9 u

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

10 u = 140

1 u = 140 ÷ 10 = 14

Amount that Ivory paid more for the pair of flippers than the jacket
= 9 u - 1 u
= 8 u
= 8 x 14
= $112

Answer(s): $112
