Answer 1

Answer:

44100

Step-by-step explanation:

end of the 2015 means the beginning of the 2016.

the beginning of 2016, the population was 40,000.

increasing rate 5%

so, after 2 years (the beginning of 2018), the population would be,

40000 (1+5/100)^2

=40000 (105/100)^2

=40000×(11025/10000)

=44100

the population would be 44100 in the beginning of 2018.
