40100 =
25 Gabby spent: Gabby's total = 2 : 5
Amount that Nora spent
= 2 x 2 u
= 4 u
Amount that the three girls spent
= 2 u + 4 u + 240
= 6 u + 240
Amount that the three girls spent
= 1346 - 452
= $894
6 u + 240 = 894
6 u = 894 - 240
6 u = 654
1 u = 654 ÷ 6 = 109
Amount that Gem and Nora had in the end
= 452 - 3 u
= 452 - 3 x 109
= 452 - 327
= $125
Answer(s): $125
