| Before |
2 u + 66 |
3 u + 25 |
151 |
| Change |
- 66 |
- 25 |

| After |
2 u |
3 u |

Amount that Sam had spent
= 66 - 41
= $25
Total amount that Tim and Sam had at first
= 2 u + 66 + 3 u + 25
= 5 u + 91
5 u + 91 = 151
5 u = 151 - 91
5 u = 60
1 u = 60 ÷ 5 = 12
Amount that Tim had at first
= 3 u + 66
= 3 x 12 + 66
= 36 + 66
= $102
Answer(s): $102
