Anna had an equal number of kiwis and mangosteens at first. She sold half of the mangosteens and bought another 28 kiwis. In the end, she had six times as many kiwis as mangosteens. Find the number of mangosteens she had at first.
| |
Kiwis |
Mangosteens |
| Before |
6 u - 28 |
2 u |
| Change |
+ 28 |
- 1 u |
| After |
6 u |
1 u |
The number of kiwis and mangosteens at first is the same.
6 u - 28 = 2 u
6 u - 2 u = 28
4 u = 28
1 u = 28 ÷ 4 = 7
Number of mangosteens that Anna had at first
= 2 u
= 2 x 7
= 14
Answer(s): 14
