Answer provided by our tutors

the function to model the population growth as


P(t) = 18450(1+ 0.027)^t


where P(t) represents the population after t years


a) what is the population after 10 years?


t = 10 years


P(10) = 18450(1+ 0.027)^10


P(10) = 24,082 people

after 10 years the population is 24,082 people.



b) how long will it take for its population of 18,450 people to double at this growth rate? explain how you foubd your answer


we need to find t such that P(t) = 2*18,450 and also P(t) = 18450(1+ 0.027)^t


18450(1+ 0.027)^t = 2*18450


t = 26 years
