| Change 1 |
- $19 |
+ $19 |
|
| Change 2 |
+ $28 |
- $28 |
|
| After |
1 u + $17 |
1 u |
$199 |
Total amount that Jeremy and Sam had
= 1 u + 1 u + $17
= 2 u + 17
2 u + 17 = 199
2 u = 199 - 17
2 u = 182
1 u = 182 ÷ 2 = 91
Amount that Jeremy had in the end
= 1 u + 17
= 91 + 17
= $108
Amount that Jeremy had at first
= 108 - 28 + 19
= $99
Answer(s): $99
