Hilda paid a total of $200 for a cardigan, a pair of socks and a pair of flippers. She spent ³₅ of her money on the pair of socks. The pair of flippers cost 4 times as much as the cardigan. How much more did she pay for the pair of flippers than the cardigan?
Amount that Hilda paid for the pair of socks
= ³₅ x 200 
= $120

Amount that Hilda left after buying the socks
= 200 - 120
= $80

Amount that Hilda paid for the cardigan = 1 u
Amount that Hilda paid for the flippers = 4 u

Total amount spent on the cardigan and the pair of flippers
= 1 u + 4 u
= 5 u

5 u = 80

1 u = 80 ÷ 5 = 16

Amount that Hilda paid more for the pair of flippers than the cardigan
= 4 u - 1 u
= 3 u
= 3 x 16
= $48

Answer(s): $48
