$100 |
| Change 1 |
- $15 |
+ $15 |
|
| Change 2 |
+ $36 |
- $36 |
|
| After |
1 u + $26 |
1 u |
$100 |
Total amount that Fred and Zane had
= 1 u + 1 u + $26
= 2 u + 26
2 u + 26 = 100
2 u = 100 - 26
2 u = 74
1 u = 74 ÷ 2 = 37
Amount that Fred had in the end
= 1 u + 26
= 37 + 26
= $63
Amount that Fred had at first
= 63 - 36 + 15
= $42
Answer(s): $42
