Gillian had an equal number of lemons and dates at first. She sold half of the dates and bought another 96 lemons. In the end, she had four times as many lemons as dates. Find the number of dates she had at first.

Dates |
Lemons |
| Before |
2 u |
4 u - 96 |
| Change |
- 1 u |
+ 96 |
| After |
1 u |
4 u |
The number of lemons and dates at first is the same.
4 u - 96 = 2 u
4 u - 2 u = 96
2 u = 96
1 u = 96 ÷ 2 = 48
Number of dates that she had at first
= 2 u
= 2 x 48
= 96
Answer(s): 96
