12 Roshel spent: Roshel's total = 1 : 2
Amount that Cathy spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 267
= 4 u + 267
Amount that the three girls spent
= 1226 - 527
= $699
4 u + 267 = 699
4 u = 699 - 267
4 u = 432
1 u = 432 ÷ 4 = 108
Amount that Lucy and Cathy had in the end
= 527 - 1 u
= 527 - 1 x 108
= 527 - 108
= $419
Answer(s): $419
