Eric and Daniel shared equally a bunch of lychees. After Eric had eaten 40 of his lychees and Daniel had eaten 20 of his, Daniel had 5 times as many lychees left as Eric. How many lychees had each of them at first?
| |
Eric |
Daniel |
| Before |
1 u + 40 |
5 u + 20 |
| Change |
- 40 |
- 20 |
| After |
1 u |
5 u |
Number of lychees each had at first was the same.
5 u + 20 = 1 u + 40
5 u - 1 u = 40 - 20
4 u = 20
1 u = 20 ÷ 4 = 5
Number of lychees that they had each at first
= 1 u + 40
= 5 + 40
= 45
Answer(s): 45
