Answer: a 470
Step-by-step explanation:
The exponential growth equation with rate of growth r in time period t is given by :-
[tex]y=A(1+r)^t[/tex], where A is the initial amount
Given : The rate of growth of population every year : 0.9% =0.009
The initial population = 430
Then , the exponential growth equation in time period t is given by :-
[tex]y=430(1+0.009)^t[/tex]
In 2010 or for t= 10 years
The projected population of the town will be :-
[tex]y=430(1.009)^{10}=470.305565305\approx470[/tex]
Hence, the projected population of the town in 2010 is about 470.
