40100 =
25 Jaslyn spent: Jaslyn's total = 2 : 5
Amount that Erika spent
= 3 x 2 u
= 6 u
Amount that the three girls spent
= 2 u + 6 u + 293
= 8 u + 293
Amount that the three girls spent
= 1580 - 543
= $1037
8 u + 293 = 1037
8 u = 1037 - 293
8 u = 744
1 u = 744 ÷ 8 = 93
Amount that Wendy and Erika had in the end
= 543 - 3 u
= 543 - 3 x 93
= 543 - 279
= $264
Answer(s): $264
