| Before |
3 u + $76.30 |
3 u |
$76.30 |
| Change |
|
- 2 u |
|
| After |
3 u + $76.30 |
1 u |
2 u + $76.30 |
Vincent had $109.70 more than Carl in the end.
3 u + 76.30 - 1 u = 109.70
2 u + 76.30 = 109.70
2 u = 109.70 - 76.30
2 u = 33.40
1 u = 33.40 ÷ 2 = 16.70
Amount that Vincent had at first
= 3 u + 76.30
= 3 x 16.70 + 76.30
= 50.10 + 76.30
= $126.40
Answer(s): $126.40
