David had 3 times as much money as Valen. After Valen's father gave Valen $32, the amount of money David had become $4 less than that of Valen's. How much did Valen have in the end?

Valen |
David |
| Before |
1 u |
3 u |
| Change |
+ $32 |
|
| After |
1 u + $32 |
3 u |
The amount that David had remains unchanged.
If David had another $4, Valen and David would have the same amount in the end.
3 u + 4 = 1 u + 32
3 u - 1 u = 32 - 4
2 u = 32 - 4
2 u = 28
1 u = 28 ÷ 2 = 14
Amount that Valen had in the end
= 1 u + 32
= 14 + 32
= $46
Answer(s): $46
