Vaidev had 3 times as much money as Paul. After Paul's father gave Paul $28, the amount of money Vaidev had become $4 less than that of Paul's. How much did Paul have in the end?
| |
Paul |
Vaidev |
| Before |
1 u |
3 u |
| Change |
+ $28 |
|
| After |
1 u + $28 |
3 u |
The amount that Vaidev had remains unchanged.
If Vaidev had another $4, Paul and Vaidev would have the same amount in the end.
3 u + 4 = 1 u + 28
3 u - 1 u = 28 - 4
2 u = 28 - 4
2 u = 24
1 u = 24 ÷ 2 = 12
Amount that Paul had in the end
= 1 u + 28
= 12 + 28
= $40
Answer(s): $40
