| Before |
8 u |
1 u |
| Change |
- 4 u |

| After |
4 u |
1 u |
Amount that Bobby had after he spent half of his money
= 8 u ÷ 2
= 4 u
Amount that Bobby had more than Jeremy in the end
= 4 u - 1 u
= 3 u
3 u = 42
1 u = 42 ÷ 3 = 14
Amount that Bobby had at first
= 8 u
= 8 x 42
= $336
Answer(s): $336
