25100 =
14 Tammy spent: Tammy's total = 1 : 4
Amount that Winnie spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 254
= 3 u + 254
Amount that the three girls spent
= 930 - 409
= $521
3 u + 254 = 521
3 u = 521 - 254
3 u = 267
1 u = 267 ÷ 3 = 89
Amount that Roshel and Winnie had in the end
= 409 - 3 u
= 409 - 3 x 89
= 409 - 267
= $142
Answer(s): $142
