| Before |
4 u + $43.50 |
4 u |
$43.50 |
| Change |
|
- 3 u |
|
| After |
4 u + $43.50 |
1 u |
3 u + $43.50 |
Paul had $102.30 more than Ethan in the end.
4 u + 43.50 - 1 u = 102.30
3 u + 43.50 = 102.30
3 u = 102.30 - 43.50
3 u = 58.80
1 u = 58.80 ÷ 3 = 19.60
Amount that Paul had at first
= 4 u + 43.50
= 4 x 19.60 + 43.50
= 78.40 + 43.50
= $121.90
Answer(s): $121.90
