25100 =
14 Emma spent: Emma's total = 1 : 4
Amount that Dana spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 261
= 3 u + 261
Amount that the three girls spent
= 1151 - 674
= $477
3 u + 261 = 477
3 u = 477 - 261
3 u = 216
1 u = 216 ÷ 3 = 72
Amount that Winnie and Dana had in the end
= 674 - 3 u
= 674 - 3 x 72
= 674 - 216
= $458
Answer(s): $458
