| After |
7 u + 49 |
9 u + 7 |
If Fiona received another $8 in the end, she would have the same amount of money as Yen.
9 u + 7 + 8 = 7 u + 49
9 u + 15 = 7 u + 49
9 u - 7 u = 49 - 15
2 u = 34
1 u = 34 ÷ 2 = 17
Amount that the girls had in the end
= 7 u + 49 + 9 u + 7
= 7 u + 9 u + 49 + 7
= 16 u + 56
= 16 x 17 + 56
= $328
Answer(s): $328
