Penelope had an equal number of starfruits and guavas at first. She sold one-sixth of the guavas and bought another 14 starfruits. In the end, she had four times as many starfruits as guavas. Find the number of guavas she had at first.
|
Starfruits |
Guavas |
Before |
20 u - 14 |
6 u |
Change |
+ 14 |
- 1 u |
After |
20 u |
5 u |
The number of starfruits and guavas at first is the same.
20 u - 14 = 6 u
20 u - 6 u = 14
14 u = 14
1 u = 14 ÷ 14 = 1
Number of guavas that Penelope had at first
= 6 u
= 6 x 1
= 6
Answer(s): 6
