50100 =
12 Betty spent: Betty's total = 1 : 2
Amount that Raeann spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 156
= 4 u + 156
Amount that the three girls spent
= 1592 - 752
= $840
4 u + 156 = 840
4 u = 840 - 156
4 u = 684
1 u = 684 ÷ 4 = 171
Amount that Gwen and Raeann had in the end
= 752 - 1 u
= 752 - 1 x 171
= 752 - 171
= $581
Answer(s): $581
