Dana had an equal number of guavas and coconuts at first. She sold one-quarter of the coconuts and bought another 82 guavas. In the end, she had twice as many guavas as coconuts. Find the number of coconuts she had at first.

Coconuts |
Guavas |
| Before |
4 u |
6 u - 82 |
| Change |
- 1 u |
+ 82 |
| After |
3 u |
6 u |
The number of guavas and coconuts at first is the same.
6 u - 82 = 4 u
6 u - 4 u = 82
2 u = 82
1 u = 82 ÷ 2 = 41
Number of coconuts that she had at first
= 4 u
= 4 x 41
= 164
Answer(s): 164
