population growth can be modeled using the formula

p=cr^t, where C is the initial population, r is the growth factor, and t is time in years

p = 20,030

C = 14,700

t = 5 years

r = ?

20030 = 14700*r^5

r^5 = 20030/14700

r = 1.064

the 5 year growth factor is 1.064.

the percent growth rate PR in 5 years is calculated by the formula

PR = ((p - C)/C)*100*(1/5)

PR = ((20030 - 14700)/14700)*100*(1/5)

PR = (5330/14700)*100*(1/5)

PR = %36.26*(1/5)

PR = 7.2517%

The population of Mathville grew %36.26 in the 5 years or at an rate of 7.2517% annually.
