Shannon had an equal number of kiwis and guavas at first. She sold half of the guavas and bought another 28 kiwis. In the end, she had four times as many kiwis as guavas. Find the number of guavas she had at first.
| |
Kiwis |
Guavas |
| Before |
4 u - 28 |
2 u |
| Change |
+ 28 |
- 1 u |
| After |
4 u |
1 u |
The number of kiwis and guavas at first is the same.
4 u - 28 = 2 u
4 u - 2 u = 28
2 u = 28
1 u = 28 ÷ 2 = 14
Number of guavas that Shannon had at first
= 2 u
= 2 x 14
= 28
Answer(s): 28
