Mary paid a total of $175 for a sweater, a pair of socks and a pair of moccasins. She spent ³₅ of her money on the pair of socks. The pair of moccasins cost 9 times as much as the sweater. How much more did she pay for the pair of moccasins than the sweater?
Amount that Mary paid for the pair of socks
= ³₅ x 175 
= $105

Amount that Mary left after buying the socks
= 175 - 105
= $70

Amount that Mary paid for the sweater = 1 u
Amount that Mary paid for the moccasins = 9 u

Total amount spent on the sweater and the pair of moccasins
= 1 u + 9 u
= 10 u

10 u = 70

1 u = 70 ÷ 10 = 7

Amount that Mary paid more for the pair of moccasins than the sweater
= 9 u - 1 u
= 8 u
= 8 x 7
= $56

Answer(s): $56
