22752
Explanations:Let the initial population be P
P = 16000
Let the annual growth rate be represented as r
r = 4.5%
let the time be represented as t
t = 8 years
Let the population after 8 years be represented as A
[tex]A\text{ = }P(\text{ 1 + }r)^t[/tex]Substitute the values of P, r, and t into the equation above
[tex]\begin{gathered} A\text{ = 16000(1 + }0.045)^8 \\ A=16000(1.045)^8 \\ A\text{ = }16000(1.422) \\ A\text{ = }22752 \end{gathered}[/tex]The population after 8 years is 22752
