Gabby had an equal number of kiwis and dates at first. She sold half of the dates and bought another 36 kiwis. In the end, she had five times as many kiwis as dates. Find the number of dates she had at first.

Dates |
Kiwis |
| Before |
2 u |
5 u - 36 |
| Change |
- 1 u |
+ 36 |
| After |
1 u |
5 u |
The number of kiwis and dates at first is the same.
5 u - 36 = 2 u
5 u - 2 u = 36
3 u = 36
1 u = 36 ÷ 3 = 12
Number of dates that she had at first
= 2 u
= 2 x 12
= 24
Answer(s): 24
