Gwen had an equal number of kiwis and dates at first. She sold one-quarter of the dates and bought another 64 kiwis. In the end, she had twice as many kiwis as dates. Find the number of dates she had at first.

Dates |
Kiwis |
| Before |
4 u |
6 u - 64 |
| Change |
- 1 u |
+ 64 |
| After |
3 u |
6 u |
The number of kiwis and dates at first is the same.
6 u - 64 = 4 u
6 u - 4 u = 64
2 u = 64
1 u = 64 ÷ 2 = 32
Number of dates that she had at first
= 4 u
= 4 x 32
= 128
Answer(s): 128
