| After |
3 u + 49 |
5 u + 9 |
If Tiffany received another $2 in the end, she would have the same amount of money as Marion.
5 u + 9 + 2 = 3 u + 49
5 u + 11 = 3 u + 49
5 u - 3 u = 49 - 11
2 u = 38
1 u = 38 ÷ 2 = 19
Amount that the girls had in the end
= 3 u + 49 + 5 u + 9
= 3 u + 5 u + 49 + 9
= 8 u + 58
= 8 x 19 + 58
= $210
Answer(s): $210
