| Change 1 |
- $11 |
+ $11 |

| Change 2 |
+ $36 |
- $36 |
|
| After |
1 u + $10 |
1 u |
$160 |
Total amount that Glen and Lee had
= 1 u + 1 u + $10
= 2 u + 10
2 u + 10 = 160
2 u = 160 - 10
2 u = 150
1 u = 150 ÷ 2 = 75
Amount that Glen had in the end
= 1 u + 10
= 75 + 10
= $85
Amount that Glen had at first
= 85 - 36 + 11
= $60
Answer(s): $60
