40% =
40100 =
25 Jane spent: Jane's total = 2 : 5
Amount that Fanny spent
= 4 x 2 u
= 8 u
Amount that the three girls spent
= 2 u + 8 u + 278
= 10 u + 278
Amount that the three girls spent
= 2334 - 766
= $1568
10 u + 278 = 1568
10 u = 1568 - 278
10 u = 1290
1 u = 1290 ÷ 10 = 129
Amount that Tiffany and Fanny had in the end
= 766 - 3 u
= 766 - 3 x 129
= 766 - 387
= $379
Answer(s): $379
