Julie had an equal number of lemons and avocados at first. She sold half of the avocados and bought another 46 lemons. In the end, she had four times as many lemons as avocados. Find the number of avocados she had at first.

Avocados |
Lemons |
| Before |
2 u |
4 u - 46 |
| Change |
- 1 u |
+ 46 |
| After |
1 u |
4 u |
The number of lemons and avocados at first is the same.
4 u - 46 = 2 u
4 u - 2 u = 46
2 u = 46
1 u = 46 ÷ 2 = 23
Number of avocados that she had at first
= 2 u
= 2 x 23
= 46
Answer(s): 46
