20100 =
15 Roshel spent: Roshel's total = 1 : 5
Amount that Shiyun spent
= 2 x 1 u
= 2 u
Amount that the three girls spent
= 1 u + 2 u + 206
= 3 u + 206
Amount that the three girls spent
= 1479 - 796
= $683
3 u + 206 = 683
3 u = 683 - 206
3 u = 477
1 u = 477 ÷ 3 = 159
Amount that Diana and Shiyun had in the end
= 796 - 4 u
= 796 - 4 x 159
= 796 - 636
= $160
Answer(s): $160
