25100 =
14 Cindy spent: Cindy's total = 1 : 4
Amount that Min spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 115
= 5 u + 115
Amount that the three girls spent
= 1611 - 776
= $835
5 u + 115 = 835
5 u = 835 - 115
5 u = 720
1 u = 720 ÷ 5 = 144
Amount that Roshel and Min had in the end
= 776 - 3 u
= 776 - 3 x 144
= 776 - 432
= $344
Answer(s): $344
