Another town's population could be modeled by the function P(t)=27,400(1.66)^t/10, where P represents the population and t represents the time, in years, since 2005. Based on the model, by approximately what percent does the population of this town increase each year?
Thank you in advance!

P(t)=27,400(1.66)^t/10
2018 - 2005 = 13 years.
P(13) =27,400 x ((1.66)^1/13) / 10
((1.66)^1/13) / 10
(1.03976 - 1) / 10
0.03976 / 10 =0.003976
0.003976 x 100 =0.3976% =~0.4% - annual pecentage increase in the population of this town.
