Rael had 3 times as much money as Vincent. After Vincent's father gave Vincent $31, the amount of money Rael had become $5 less than that of Vincent's. How much did Vincent have in the end?

Vincent |
Rael |
| Before |
1 u |
3 u |
| Change |
+ $31 |
|
| After |
1 u + $31 |
3 u |
The amount that Rael had remains unchanged.
If Rael had another $5, Vincent and Rael would have the same amount in the end.
3 u + 5 = 1 u + 31
3 u - 1 u = 31 - 5
2 u = 31 - 5
2 u = 26
1 u = 26 ÷ 2 = 13
Amount that Vincent had in the end
= 1 u + 31
= 13 + 31
= $44
Answer(s): $44
