40% =
40100 =
25 Zara spent: Zara's total = 2 : 5
Amount that Fanny spent
= 2 x 2 u
= 4 u
Amount that the three girls spent
= 2 u + 4 u + 135
= 6 u + 135
Amount that the three girls spent
= 1324 - 469
= $855
6 u + 135 = 855
6 u = 855 - 135
6 u = 720
1 u = 720 ÷ 6 = 120
Amount that Barbara and Fanny had in the end
= 469 - 3 u
= 469 - 3 x 120
= 469 - 360
= $109
Answer(s): $109
