Vanessa had an equal number of coconuts and apples at first. She sold one-quarter of the apples and bought another 66 coconuts. In the end, she had twice as many coconuts as apples. Find the number of apples she had at first.

Apples |
Coconuts |
| Before |
4 u |
6 u - 66 |
| Change |
- 1 u |
+ 66 |
| After |
3 u |
6 u |
The number of coconuts and apples at first is the same.
6 u - 66 = 4 u
6 u - 4 u = 66
2 u = 66
1 u = 66 ÷ 2 = 33
Number of apples that she had at first
= 4 u
= 4 x 33
= 132
Answer(s): 132
