| Change 1 |
- $10 |
+ $10 |
|
| Change 2 |
+ $24 |
- $24 |
|
| After |
1 u + $24 |
1 u |
$194 |
Total amount that Riordan and Paul had
= 1 u + 1 u + $24
= 2 u + 24
2 u + 24 = 194
2 u = 194 - 24
2 u = 170
1 u = 170 ÷ 2 = 85
Amount that Riordan had in the end
= 1 u + 24
= 85 + 24
= $109
Amount that Riordan had at first
= 109 - 24 + 10
= $95
Answer(s): $95
