| Change 1 |
- $17 |

| Change 2 |
+ $20 |
- $20 |

| After |
1 u + $13 |
1 u |
$185 |
Total amount that Gabriel and Charlie had
= 1 u + 1 u + $13
= 2 u + 13
2 u + 13 = 185
2 u = 185 - 13
2 u = 172
1 u = 172 ÷ 2 = 86
Amount that Gabriel had in the end
= 1 u + 13
= 86 + 13
= $99
Amount that Gabriel had at first
= 99 - 20 + 17
= $96
Answer(s): $96
