50% =
50100 =
12 Marion spent: Marion's total = 1 : 2
Amount that Xandra spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 223
= 3 u + 223
Amount that the three girls spent
= 1173 - 554
= $619
3 u + 223 = 619
3 u = 619 - 223
3 u = 396
1 u = 396 ÷ 3 = 132
Amount that Wendy and Xandra had in the end
= 554 - 1 u
= 554 - 1 x 132
= 554 - 132
= $422
Answer(s): $422
