50100 =
12 Wendy spent: Wendy's total = 1 : 2
Amount that Joelle spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 256
= 5 u + 256
Amount that the three girls spent
= 1705 - 729
= $976
5 u + 256 = 976
5 u = 976 - 256
5 u = 720
1 u = 720 ÷ 5 = 144
Amount that Gabby and Joelle had in the end
= 729 - 1 u
= 729 - 1 x 144
= 729 - 144
= $585
Answer(s): $585
