| After |
2 u + 46 |
7 u + 4 |
If Linda received another $7 in the end, she would have the same amount of money as Tammy.
7 u + 4 + 7 = 2 u + 46
7 u + 11 = 2 u + 46
7 u - 2 u = 46 - 11
5 u = 35
1 u = 35 ÷ 5 = 7
Amount that the girls had in the end
= 2 u + 46 + 7 u + 4
= 2 u + 7 u + 46 + 4
= 9 u + 50
= 9 x 7 + 50
= $113
Answer(s): $113
