Nicole paid a total of $216 for a hoodie, a pair of socks and a pair of trainers. She spent ⁴₉ of her money on the pair of socks. The pair of trainers cost 3 times as much as the hoodie. How much more did she pay for the pair of trainers than the hoodie?
Amount that Nicole paid for the pair of socks
= ⁴₉ x 216 
= $96

Amount that Nicole left after buying the socks
= 216 - 96
= $120

Amount that Nicole paid for the hoodie = 1 u
Amount that Nicole paid for the trainers = 3 u

Total amount spent on the hoodie and the pair of trainers
= 1 u + 3 u
= 4 u

4 u = 120

1 u = 120 ÷ 4 = 30

Amount that Nicole paid more for the pair of trainers than the hoodie
= 3 u - 1 u
= 2 u
= 2 x 30
= $60

Answer(s): $60
