| Before |
3 u + $53.50 |
3 u |

| Change |

- 2 u |
|
| After |
3 u + $53.50 |
1 u |
2 u + $53.50 |
Julian had $65.90 more than Ken in the end.
3 u + 53.50 - 1 u = 65.90
2 u + 53.50 = 65.90
2 u = 65.90 - 53.50
2 u = 12.40
1 u = 12.40 ÷ 2 = 6.20
Amount that Julian had at first
= 3 u + 53.50
= 3 x 6.20 + 53.50
= 18.60 + 53.50
= $72.10
Answer(s): $72.10
