20100 =
15 Xandra spent: Xandra's total = 1 : 5
Amount that Roshel spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 300
= 5 u + 300
Amount that the three girls spent
= 1249 - 589
= $660
5 u + 300 = 660
5 u = 660 - 300
5 u = 360
1 u = 360 ÷ 5 = 72
Amount that Zara and Roshel had in the end
= 589 - 4 u
= 589 - 4 x 72
= 589 - 288
= $301
Answer(s): $301
