Nicole had an equal number of kiwis and pomegranates at first. She sold half of the pomegranates and bought another 90 kiwis. In the end, she had four times as many kiwis as pomegranates. Find the number of pomegranates she had at first.
| |
Pomegranates |
Kiwis |
| Before |
2 u |
4 u - 90 |
| Change |
- 1 u |
+ 90 |
| After |
1 u |
4 u |
The number of kiwis and pomegranates at first is the same.
4 u - 90 = 2 u
4 u - 2 u = 90
2 u = 90
1 u = 90 ÷ 2 = 45
Number of pomegranates that she had at first
= 2 u
= 2 x 45
= 90
Answer(s): 90
