Gillian had an equal number of kiwis and pomegranates at first. She sold half of the pomegranates and bought another 21 kiwis. In the end, she had five times as many kiwis as pomegranates. Find the number of pomegranates she had at first.
| |
Kiwis |
Pomegranates |
| Before |
5 u - 21 |
2 u |
| Change |
+ 21 |
- 1 u |
| After |
5 u |
1 u |
The number of kiwis and pomegranates at first is the same.
5 u - 21 = 2 u
5 u - 2 u = 21
3 u = 21
1 u = 21 ÷ 3 = 7
Number of pomegranates that Gillian had at first
= 2 u
= 2 x 7
= 14
Answer(s): 14
