| After |
5 u + 32 |
8 u + 3 |
If Zoe received another $8 in the end, she would have the same amount of money as Tina.
8 u + 3 + 8 = 5 u + 32
8 u + 11 = 5 u + 32
8 u - 5 u = 32 - 11
3 u = 21
1 u = 21 ÷ 3 = 7
Amount that the girls had in the end
= 5 u + 32 + 8 u + 3
= 5 u + 8 u + 32 + 3
= 13 u + 35
= 13 x 7 + 35
= $126
Answer(s): $126
