| Before |
3 u + 24 |
11 u + 14 |
136 |
| Change |
- 24 |
- 14 |

| After |
3 u |
11 u |

Amount that Valen had spent
= 24 - 10
= $14
Total amount that Ben and Valen had at first
= 3 u + 24 + 11 u + 14
= 14 u + 38
14 u + 38 = 136
14 u = 136 - 38
14 u = 98
1 u = 98 ÷ 14 = 7
Amount that Ben had at first
= 11 u + 24
= 11 x 7 + 24
= 77 + 24
= $101
Answer(s): $101
