| Before |
7 u + $95.40 |
7 u |

- 3 u |
|
| After |
7 u + $95.40 |
4 u |
3 u + $95.40 |
Ken had $108.90 more than Albert in the end.
7 u + 95.40 - 4 u = 108.90
3 u + 95.40 = 108.90
3 u = 108.90 - 95.40
3 u = 13.50
1 u = 13.50 ÷ 3 = 4.50
Amount that Ken had at first
= 7 u + 95.40
= 7 x 4.50 + 95.40
= 31.50 + 95.40
= $126.90
Answer(s): $126.90
