Answer 1

Answer:

Population in 2013  =   3541

Step-by-step explanation:

Population in 2008   =  3800

Decrease in population every year = 1.4 %

To Find :

Population in 2013

=> Population after 5 Years

Population in 2013  = Population in 2008 * (  1  -  Rate of Decrease/100)^(number of Years)

=> Population in 2013  =  3800 (1 - 1.4/100)⁵

=>  Population in 2013  =   3800 ( 0.986)⁵

=>  Population in 2013  =   3541
