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

| Change 2 |
+ $23 |
- $23 |

| After |
1 u + $17 |
1 u |
$155 |
Total amount that Fred and Neave had
= 1 u + 1 u + $17
= 2 u + 17
2 u + 17 = 155
2 u = 155 - 17
2 u = 138
1 u = 138 ÷ 2 = 69
Amount that Fred had in the end
= 1 u + 17
= 69 + 17
= $86
Amount that Fred had at first
= 86 - 23 + 17
= $80
Answer(s): $80
