25% =
25100 =
14 Roshel spent: Roshel's total = 1 : 4
Amount that Shiyun spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 157
= 3 u + 157
Amount that the three girls spent
= 1172 - 721
= $451
3 u + 157 = 451
3 u = 451 - 157
3 u = 294
1 u = 294 ÷ 3 = 98
Amount that Fiona and Shiyun had in the end
= 721 - 3 u
= 721 - 3 x 98
= 721 - 294
= $427
Answer(s): $427
