4 u + 45 |
11 u + 8 |
If Fanny received another $9 in the end, she would have the same amount of money as Fiona.
11 u + 8 + 9 = 4 u + 45
11 u + 17 = 4 u + 45
11 u - 4 u = 45 - 17
7 u = 28
1 u = 28 ÷ 7 = 4
Amount that the girls had in the end
= 4 u + 45 + 11 u + 8
= 4 u + 11 u + 45 + 8
= 15 u + 53
= 15 x 4 + 53
= $113
Answer(s): $113
