Michael |
Sam |
| Before |
10 u |
1 u |
| Change |
- 5 u |
|
| After |
5 u |
1 u |
Amount that Michael had after he spent half of his money
= 10 u ÷ 2
= 5 u
Amount that Michael had more than Sam in the end
= 5 u - 1 u
= 4 u
4 u = 32
1 u = 32 ÷ 4 = 8
Amount that Michael had at first
= 10 u
= 10 x 32
= $320
Answer(s): $320
