Pierre |
Ethan |
| Before |
4 u |
1 u |
| Change |
- 2 u |
|
| After |
2 u |
1 u |
Amount that Pierre had after he spent half of his money
= 4 u ÷ 2
= 2 u
Amount that Pierre had more than Ethan in the end
= 2 u - 1 u
= 1 u
1 u = 50
Amount that Pierre had at first
= 4 u
= 4 x 50
= $200
Answer(s): $200
