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 470
b 500
c 503
d 289

a 470

Step-by-step explanation:

The exponential growth equation with rate of growth r in time period t is given by :-

, 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 :-

In 2010 or for t= 10 years

The projected population of the town will be :-

Hence, the projected population of the town in 2010 is about 470.
