Kimberly paid a total of $230 for a sweater, a pair of socks and a pair of sneakers. She spent ³₅ of her money on the pair of socks. The pair of sneakers cost 3 times as much as the sweater. How much more did she pay for the pair of sneakers than the sweater?
Amount that Kimberly paid for the pair of socks
= ³₅ x 230 
= $138

Amount that Kimberly left after buying the socks
= 230 - 138
= $92

Amount that Kimberly paid for the sweater = 1 u
Amount that Kimberly paid for the sneakers = 3 u

Total amount spent on the sweater and the pair of sneakers
= 1 u + 3 u
= 4 u

4 u = 92

1 u = 92 ÷ 4 = 23

Amount that Kimberly paid more for the pair of sneakers than the sweater
= 3 u - 1 u
= 2 u
= 2 x 23
= $46

Answer(s): $46
