40% =
40100 =
25 Fanny spent: Fanny's total = 2 : 5
Amount that Gabby spent
= 3 x 2 u
= 6 u
Amount that the three girls spent
= 2 u + 6 u + 205
= 8 u + 205
Amount that the three girls spent
= 1450 - 781
= $669
8 u + 205 = 669
8 u = 669 - 205
8 u = 464
1 u = 464 ÷ 8 = 58
Amount that Gem and Gabby had in the end
= 781 - 3 u
= 781 - 3 x 58
= 781 - 174
= $607
Answer(s): $607
