Jade had an equal number of limes and avocados at first. She sold one-third of the avocados and bought another 40 limes. In the end, she had four times as many limes as avocados. Find the number of avocados she had at first.

Avocados |
Limes |
| Before |
3 u |
8 u - 40 |
| Change |
- 1 u |
+ 40 |
| After |
2 u |
8 u |
The number of limes and avocados at first is the same.
8 u - 40 = 3 u
8 u - 3 u = 40
5 u = 40
1 u = 40 ÷ 5 = 8
Number of avocados that she had at first
= 3 u
= 3 x 8
= 24
Answer(s): 24
