Bobby and Fabian shared equally a bunch of lychees. After Bobby had eaten 45 of his lychees and Fabian had eaten 31 of his, Fabian had 3 times as many lychees left as Bobby. How many lychees had each of them at first?
| |
Bobby |
Fabian |
| Before |
1 u + 45 |
3 u + 31 |
| Change |
- 45 |
- 31 |
| After |
1 u |
3 u |
Number of lychees each had at first was the same.
3 u + 31 = 1 u + 45
3 u - 1 u = 45 - 31
2 u = 14
1 u = 14 ÷ 2 = 7
Number of lychees that they had each at first
= 1 u + 45
= 7 + 45
= 52
Answer(s): 52
