25100 =
14 Rachel spent: Rachel's total = 1 : 4
Amount that Gillian spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 175
= 4 u + 175
Amount that the three girls spent
= 1042 - 443
= $599
4 u + 175 = 599
4 u = 599 - 175
4 u = 424
1 u = 424 ÷ 4 = 106
Amount that Roshel and Gillian had in the end
= 443 - 3 u
= 443 - 3 x 106
= 443 - 318
= $125
Answer(s): $125
