| Change 1 |
- $17 |
+ $17 |

| Change 2 |
+ $34 |
- $34 |
|
| After |
1 u + $18 |
1 u |
$182 |
Total amount that Eric and Valen had
= 1 u + 1 u + $18
= 2 u + 18
2 u + 18 = 182
2 u = 182 - 18
2 u = 164
1 u = 164 ÷ 2 = 82
Amount that Eric had in the end
= 1 u + 18
= 82 + 18
= $100
Amount that Eric had at first
= 100 - 34 + 17
= $83
Answer(s): $83
