40% =
40100 =
25 Roshel spent: Roshel's total = 2 : 5
Amount that Dana spent
= 2 x 2 u
= 4 u
Amount that the three girls spent
= 2 u + 4 u + 161
= 6 u + 161
Amount that the three girls spent
= 1475 - 522
= $953
6 u + 161 = 953
6 u = 953 - 161
6 u = 792
1 u = 792 ÷ 6 = 132
Amount that Sarah and Dana had in the end
= 522 - 3 u
= 522 - 3 x 132
= 522 - 396
= $126
Answer(s): $126
