Kimberly had an equal number of coconuts and kiwis at first. She sold one-third of the kiwis and bought another 33 coconuts. In the end, she had thrice as many coconuts as kiwis. Find the number of kiwis she had at first.
|
Kiwis |
Coconuts |
Before |
3 u |
6 u - 33 |
Change |
- 1 u |
+ 33 |
After |
2 u |
6 u |
The number of coconuts and kiwis at first is the same.
6 u - 33 = 3 u
6 u - 3 u = 33
3 u = 33
1 u = 33 ÷ 3 = 11
Number of kiwis that she had at first
= 3 u
= 3 x 11
= 33
Answer(s): 33
