Valen |

| Before |
3 u + $77.50 |
3 u |
$77.50 |
| Change |
|
- 2 u |
|
| After |
3 u + $77.50 |
1 u |
2 u + $77.50 |
Zane had $106.90 more than Valen in the end.
3 u + 77.50 - 1 u = 106.90
2 u + 77.50 = 106.90
2 u = 106.90 - 77.50
2 u = 29.40
1 u = 29.40 ÷ 2 = 14.70
Amount that Zane had at first
= 3 u + 77.50
= 3 x 14.70 + 77.50
= 44.10 + 77.50
= $121.60
Answer(s): $121.60
