50100 =
12 Gabby spent: Gabby's total = 1 : 2
Amount that Opal spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 222
= 4 u + 222
Amount that the three girls spent
= 1468 - 662
= $806
4 u + 222 = 806
4 u = 806 - 222
4 u = 584
1 u = 584 ÷ 4 = 146
Amount that Emma and Opal had in the end
= 662 - 1 u
= 662 - 1 x 146
= 662 - 146
= $516
Answer(s): $516
