Warren and David shared equally a bunch of lychees. After Warren had eaten 48 of his lychees and David had eaten 10 of his, David had 3 times as many lychees left as Warren. How many lychees had each of them at first?
|
Warren |
David |
Before |
1 u + 48 |
3 u + 10 |
Change |
- 48 |
- 10 |
After |
1 u |
3 u |
Number of lychees each had at first was the same.
3 u + 10 = 1 u + 48
3 u - 1 u = 48 - 10
2 u = 38
1 u = 38 ÷ 2 = 19
Number of lychees that they had each at first
= 1 u + 48
= 19 + 48
= 67
Answer(s): 67
