50% =
50100 =
12 Xuan spent: Xuan's total = 1 : 2
Amount that Xandra spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 295
= 3 u + 295
Amount that the three girls spent
= 1350 - 548
= $802
3 u + 295 = 802
3 u = 802 - 295
3 u = 507
1 u = 507 ÷ 3 = 169
Amount that Shiyun and Xandra had in the end
= 548 - 1 u
= 548 - 1 x 169
= 548 - 169
= $379
Answer(s): $379
