| Before |
4 u + $40.50 |
4 u |

| Change |
|
- 3 u |
|
| After |
4 u + $40.50 |
1 u |
3 u + $40.50 |
Dylan had $81.30 more than Jack in the end.
4 u + 40.50 - 1 u = 81.30
3 u + 40.50 = 81.30
3 u = 81.30 - 40.50
3 u = 40.80
1 u = 40.80 ÷ 3 = 13.60
Amount that Dylan had at first
= 4 u + 40.50
= 4 x 13.60 + 40.50
= 54.40 + 40.50
= $94.90
Answer(s): $94.90
