Valen |
Jenson |
| Before |
10 u |
1 u |
| Change |
- 5 u |
|
| After |
5 u |
1 u |
Amount that Valen had after he spent half of his money
= 10 u ÷ 2
= 5 u
Amount that Valen had more than Jenson in the end
= 5 u - 1 u
= 4 u
4 u = 40
1 u = 40 ÷ 4 = 10
Amount that Valen had at first
= 10 u
= 10 x 40
= $400
Answer(s): $400
