Total |
| Before |
2 u + 72 |
11 u + 34 |
171 |
| Change |
- 72 |
- 34 |
|
| After |
2 u |
11 u |

Amount that Ben had spent
= 72 - 38
= $34
Total amount that Charlie and Ben had at first
= 2 u + 72 + 11 u + 34
= 13 u + 106
13 u + 106 = 171
13 u = 171 - 106
13 u = 65
1 u = 65 ÷ 13 = 5
Amount that Charlie had at first
= 11 u + 72
= 11 x 5 + 72
= 55 + 72
= $127
Answer(s): $127
