25100 =
14 Cindy spent: Cindy's total = 1 : 4
Amount that Fanny spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 257
= 4 u + 257
Amount that the three girls spent
= 1500 - 647
= $853
4 u + 257 = 853
4 u = 853 - 257
4 u = 596
1 u = 596 ÷ 4 = 149
Amount that Gem and Fanny had in the end
= 647 - 3 u
= 647 - 3 x 149
= 647 - 447
= $200
Answer(s): $200
