Answer:
Yes, his estimate is reasonable. There are about 300 people living in each community.
Explanation:
1. First consider the number of counties in Kalb:
Kalb : 15,000 counties
2. Then consider the number of communities in each Kalb County:
Number of communities per Kalb county : 50 communities
3. As the problem says that each community has about the same number of people, to know how many people there are in each community is needed to take the number of counties and divide them by the number of communities in each Kalb County, that is:
Number of people in each community =
![(Counties)/(Communities)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/vjdu8zyr0of0ftutmgpd0byy3erpqzelfp.png)
Number of people in each community =
![(15,000)/(50)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/dorg83qaz4ogindv98nk3007ybwa8hj0b4.png)
Number of people in each community = 300 people
