| Change 1 |
- $13 |
+ $13 |

| Change 2 |
+ $24 |
- $24 |

| After |
1 u + $39 |
1 u |
$149 |
Total amount that Cody and Ethan had
= 1 u + 1 u + $39
= 2 u + 39
2 u + 39 = 149
2 u = 149 - 39
2 u = 110
1 u = 110 ÷ 2 = 55
Amount that Cody had in the end
= 1 u + 39
= 55 + 39
= $94
Amount that Cody had at first
= 94 - 24 + 13
= $83
Answer(s): $83
