Oliver |
Vaidev |
| Before |
12 u |
1 u |
| Change |
- 4 u |
|
| After |
8 u |
1 u |
Amount that Oliver had after he spent one-third of his money
= 12 u ÷ 3
= 4 u
Amount that Oliver had more than Vaidev in the end
= 8 u - 1 u
= 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Amount that Oliver had at first
= 12 u
= 12 x 28
= $336
Answer(s): $336
