25% =
25100 =
14 Dana spent: Dana's total = 1 : 4
Amount that Xandra spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 228
= 3 u + 228
Amount that the three girls spent
= 1134 - 726
= $408
3 u + 228 = 408
3 u = 408 - 228
3 u = 180
1 u = 180 ÷ 3 = 60
Amount that Elyse and Xandra had in the end
= 726 - 3 u
= 726 - 3 x 60
= 726 - 180
= $546
Answer(s): $546
