| Before |
3 u + $45.60 |
3 u |

- 2 u |
|
| After |
3 u + $45.60 |
1 u |
2 u + $45.60 |
Paul had $84.20 more than Sean in the end.
3 u + 45.60 - 1 u = 84.20
2 u + 45.60 = 84.20
2 u = 84.20 - 45.60
2 u = 38.60
1 u = 38.60 ÷ 2 = 19.30
Amount that Paul had at first
= 3 u + 45.60
= 3 x 19.30 + 45.60
= 57.90 + 45.60
= $103.50
Answer(s): $103.50
