Ethan |
Ken |
| Before |
8 u |
1 u |
| Change |
- 4 u |
|
| After |
4 u |
1 u |
Amount that Ethan had after he spent half of his money
= 8 u ÷ 2
= 4 u
Amount that Ethan had more than Ken in the end
= 4 u - 1 u
= 3 u
3 u = 36
1 u = 36 ÷ 3 = 12
Amount that Ethan had at first
= 8 u
= 8 x 36
= $288
Answer(s): $288
