| Change 1 |
- $15 |
+ $15 |

| Change 2 |
+ $29 |
- $29 |
|
| After |
1 u + $23 |
1 u |
$175 |
Total amount that Henry and Perry had
= 1 u + 1 u + $23
= 2 u + 23
2 u + 23 = 175
2 u = 175 - 23
2 u = 152
1 u = 152 ÷ 2 = 76
Amount that Henry had in the end
= 1 u + 23
= 76 + 23
= $99
Amount that Henry had at first
= 99 - 29 + 15
= $85
Answer(s): $85
