Nicole paid a total of $220 for a blouse, a pair of socks and a pair of flippers. She spent ⁴₅ of her money on the pair of socks. The pair of flippers cost 3 times as much as the blouse. How much more did she pay for the pair of flippers than the blouse?
Amount that Nicole paid for the pair of socks
= ⁴₅ x 220 
= $176

Amount that Nicole left after buying the socks
= 220 - 176
= $44

Amount that Nicole paid for the blouse = 1 u
Amount that Nicole paid for the flippers = 3 u

Total amount spent on the blouse and the pair of flippers
= 1 u + 3 u
= 4 u

4 u = 44

1 u = 44 ÷ 4 = 11

Amount that Nicole paid more for the pair of flippers than the blouse
= 3 u - 1 u
= 2 u
= 2 x 11
= $22

Answer(s): $22
