| After |
3 u + 36 |
5 u + 6 |
If Elyse received another $2 in the end, she would have the same amount of money as Roshel.
5 u + 6 + 2 = 3 u + 36
5 u + 8 = 3 u + 36
5 u - 3 u = 36 - 8
2 u = 28
1 u = 28 ÷ 2 = 14
Amount that the girls had in the end
= 3 u + 36 + 5 u + 6
= 3 u + 5 u + 36 + 6
= 8 u + 42
= 8 x 14 + 42
= $154
Answer(s): $154
