$132 |
| Change 1 |
- $17 |
+ $17 |
|
| Change 2 |
+ $24 |
- $24 |
|
| After |
1 u + $16 |
1 u |
$132 |
Total amount that Ben and Lee had
= 1 u + 1 u + $16
= 2 u + 16
2 u + 16 = 132
2 u = 132 - 16
2 u = 116
1 u = 116 ÷ 2 = 58
Amount that Ben had in the end
= 1 u + 16
= 58 + 16
= $74
Amount that Ben had at first
= 74 - 24 + 17
= $67
Answer(s): $67
