| Change 1 |
- $15 |
+ $15 |
|
| Change 2 |
+ $20 |
- $20 |
|
| After |
1 u + $30 |
1 u |
$200 |
Total amount that Reggie and Sean had
= 1 u + 1 u + $30
= 2 u + 30
2 u + 30 = 200
2 u = 200 - 30
2 u = 170
1 u = 170 ÷ 2 = 85
Amount that Reggie had in the end
= 1 u + 30
= 85 + 30
= $115
Amount that Reggie had at first
= 115 - 20 + 15
= $110
Answer(s): $110
