+ 33 |
+ 5 |
| After |
5 u + 33 |
7 u + 5 |
If Zoe received another $4 in the end, she would have the same amount of money as Roshel.
7 u + 5 + 4 = 5 u + 33
7 u + 9 = 5 u + 33
7 u - 5 u = 33 - 9
2 u = 24
1 u = 24 ÷ 2 = 12
Amount that the girls had in the end
= 5 u + 33 + 7 u + 5
= 5 u + 7 u + 33 + 5
= 12 u + 38
= 12 x 12 + 38
= $182
Answer(s): $182
