| Before |
5 u + $66.40 |

- 3 u |
|
| After |
5 u + $66.40 |
2 u |
3 u + $66.40 |
Jenson had $90.10 more than Simon in the end.
5 u + 66.40 - 2 u = 90.10
3 u + 66.40 = 90.10
3 u = 90.10 - 66.40
3 u = 23.70
1 u = 23.70 ÷ 3 = 7.90
Amount that Jenson had at first
= 5 u + 66.40
= 5 x 7.90 + 66.40
= 39.50 + 66.40
= $105.90
Answer(s): $105.90
