Ryan had 4 times as much money as Paul. After Paul's father gave Paul $37, the amount of money Ryan had become $4 less than that of Paul's. How much did Paul have in the end?

Paul |
Ryan |
| Before |
1 u |
4 u |
| Change |
+ $37 |
|
| After |
1 u + $37 |
4 u |
The amount that Ryan had remains unchanged.
If Ryan had another $4, Paul and Ryan would have the same amount in the end.
4 u + 4 = 1 u + 37
4 u - 1 u = 37 - 4
3 u = 37 - 4
3 u = 33
1 u = 33 ÷ 3 = 11
Amount that Paul had in the end
= 1 u + 37
= 11 + 37
= $48
Answer(s): $48
