50100 =
12 Julie spent: Julie's total = 1 : 2
Amount that Shiyun spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 194
= 4 u + 194
Amount that the three girls spent
= 1509 - 651
= $858
4 u + 194 = 858
4 u = 858 - 194
4 u = 664
1 u = 664 ÷ 4 = 166
Amount that Emily and Shiyun had in the end
= 651 - 1 u
= 651 - 1 x 166
= 651 - 166
= $485
Answer(s): $485
