| Before |
3 u + 62 |
4 u + 50 |
133 |
| Change |
- 62 |
- 50 |
|
| After |
3 u |
4 u |

Amount that Vaidev had spent
= 62 - 12
= $50
Total amount that Paul and Vaidev had at first
= 3 u + 62 + 4 u + 50
= 7 u + 112
7 u + 112 = 133
7 u = 133 - 112
7 u = 21
1 u = 21 ÷ 7 = 3
Amount that Paul had at first
= 4 u + 62
= 4 x 3 + 62
= 12 + 62
= $74
Answer(s): $74
