Question

The population of a town in 2000 was 430. The population is increasing at a rate of 0.9% every year. What will be the projected population of the town in 2010? Round your answer to the nearest whole number.
A. 440
B. 450
C. 460
D. 470

Answer 1

Population = initial population(1 + r)^n

\[P = P_o(1+r)^n\]

P_o is the initial population (430)
r is the rate at which it is increasing (.009)
n is the number of years after 2000 (10)

so...

\[P = 430(1.90)^{10}\]

Answer 2

EDIT!***

\[P = 430(1.009)^{10}\]

Answer 3

i got 470.30

Answer 4

so D

Answer 5
