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

| Change 2 |
+ $28 |
- $28 |

| After |
1 u + $35 |
1 u |
$125 |
Total amount that Cody and Valen had
= 1 u + 1 u + $35
= 2 u + 35
2 u + 35 = 125
2 u = 125 - 35
2 u = 90
1 u = 90 ÷ 2 = 45
Amount that Cody had in the end
= 1 u + 35
= 45 + 35
= $80
Amount that Cody had at first
= 80 - 28 + 17
= $69
Answer(s): $69
