Oscar had 3 times as much money as Albert. After Albert's father gave Albert $30, the amount of money Oscar had become $6 less than that of Albert's. How much did Albert have in the end?

Albert |
Oscar |
| Before |
1 u |
3 u |
| Change |
+ $30 |
|
| After |
1 u + $30 |
3 u |
The amount that Oscar had remains unchanged.
If Oscar had another $6, Albert and Oscar would have the same amount in the end.
3 u + 6 = 1 u + 30
3 u - 1 u = 30 - 6
2 u = 30 - 6
2 u = 24
1 u = 24 ÷ 2 = 12
Amount that Albert had in the end
= 1 u + 30
= 12 + 30
= $42
Answer(s): $42
