Answer:
The population of the town in 2020 will approx. be 12,039.
Step-by-step explanation:
The initial population in the year 2017 = 10,400
Increase in population every yea r = 5%
Now, 5% of 10, 400 =
Hence, the population in the year 2018 = 10,400 + 520 = 10,920
Now, in the year 2019
5% of 10, 920 =
Hence, the population in the year 2019 = 10,920 + 546 = 11,466
Now, in the year 2020
5% of 11,466 =
or, the population in the year 2020 = 11,466 + 573.3 = 12,039.3
The population of the town in 2020 will approx. be 12,039.
