25% =
25100 =
14 Xandra spent: Xandra's total = 1 : 4
Amount that Jean spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 170
= 3 u + 170
Amount that the three girls spent
= 1116 - 529
= $587
3 u + 170 = 587
3 u = 587 - 170
3 u = 417
1 u = 417 ÷ 3 = 139
Amount that Lynn and Jean had in the end
= 529 - 3 u
= 529 - 3 x 139
= 529 - 417
= $112
Answer(s): $112
