$171 |
| Change 1 |
- $19 |
+ $19 |
|
| Change 2 |
+ $36 |
- $36 |
|
| After |
1 u + $29 |
1 u |
$171 |
Total amount that Zane and Ian had
= 1 u + 1 u + $29
= 2 u + 29
2 u + 29 = 171
2 u = 171 - 29
2 u = 142
1 u = 142 ÷ 2 = 71
Amount that Zane had in the end
= 1 u + 29
= 71 + 29
= $100
Amount that Zane had at first
= 100 - 36 + 19
= $83
Answer(s): $83
