| Change 1 |
- $19 |
+ $19 |
|
| Change 2 |
+ $27 |
- $27 |
|
| After |
1 u + $14 |
1 u |
$196 |
Total amount that Luke and Pierre had
= 1 u + 1 u + $14
= 2 u + 14
2 u + 14 = 196
2 u = 196 - 14
2 u = 182
1 u = 182 ÷ 2 = 91
Amount that Luke had in the end
= 1 u + 14
= 91 + 14
= $105
Amount that Luke had at first
= 105 - 27 + 19
= $97
Answer(s): $97
