50100 =
12 Zoe spent: Zoe's total = 1 : 2
Amount that Elyse spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 198
= 5 u + 198
Amount that the three girls spent
= 1790 - 712
= $1078
5 u + 198 = 1078
5 u = 1078 - 198
5 u = 880
1 u = 880 ÷ 5 = 176
Amount that Shiyun and Elyse had in the end
= 712 - 1 u
= 712 - 1 x 176
= 712 - 176
= $536
Answer(s): $536
