Gabby had an equal number of dates and dragon fruits at first. She sold half of the dragon fruits and bought another 46 dates. In the end, she had four times as many dates as dragon fruits. Find the number of dragon fruits she had at first.

Dates |
| Before |
2 u |
4 u - 46 |
| Change |
- 1 u |
+ 46 |
| After |
1 u |
4 u |
The number of dates and dragon fruits 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 dragon fruits that she had at first
= 2 u
= 2 x 23
= 46
Answer(s): 46
