Simon |
Ahmad |
| Before |
9 u |
1 u |
| Change |
- 3 u |
|
| After |
6 u |
1 u |
Amount that Simon had after he spent one-third of his money
= 9 u ÷ 3
= 3 u
Amount that Simon had more than Ahmad in the end
= 6 u - 1 u
= 5 u
5 u = 30
1 u = 30 ÷ 5 = 6
Amount that Simon had at first
= 9 u
= 9 x 30
= $270
Answer(s): $270
