| Before |
5 u + $89.20 |
5 u |

- 3 u |
|
| After |
5 u + $89.20 |
2 u |
3 u + $89.20 |
Jack had $106.30 more than Tim in the end.
5 u + 89.20 - 2 u = 106.30
3 u + 89.20 = 106.30
3 u = 106.30 - 89.20
3 u = 17.10
1 u = 17.10 ÷ 3 = 5.70
Amount that Jack had at first
= 5 u + 89.20
= 5 x 5.70 + 89.20
= 28.50 + 89.20
= $117.70
Answer(s): $117.70
