| After |
7 u + 46 |
9 u + 9 |
If Linda received another $9 in the end, she would have the same amount of money as Esther.
9 u + 9 + 9 = 7 u + 46
9 u + 18 = 7 u + 46
9 u - 7 u = 46 - 18
2 u = 28
1 u = 28 ÷ 2 = 14
Amount that the girls had in the end
= 7 u + 46 + 9 u + 9
= 7 u + 9 u + 46 + 9
= 16 u + 55
= 16 x 14 + 55
= $279
Answer(s): $279
