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 = ![\frac{5}{100} \times 10, 400 = 520](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B100%7D%20%5Ctimes%2010%2C%20400%20%3D%20520)
Hence, the population in the year 2018 = 10,400 + 520 = 10,920
Now, in the year 2019
5% of 10, 920 = ![\frac{5}{100} \times 10, 920 = 546](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B100%7D%20%5Ctimes%2010%2C%20920%20%3D%20546)
Hence, the population in the year 2019 = 10,920 + 546 = 11,466
Now, in the year 2020
5% of 11,466 = ![\frac{5}{100} \times 11,466 = 573.3](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B100%7D%20%5Ctimes%2011%2C466%20%3D%20573.3)
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.
