Answer:

263,606.9

Step-by-step explanation:

In 2004 the population in Morganton, Georgia, was 43,000.

(0, 43000)

The population in Morganton doubled by 2010

In 6 years the population is doubled (86000)

(6,86000)

$A= a(b)^t$

Use (0,43000) in the above equation

$A= a(b)^t\\43000= a(b)^0\\a=43000$

Now plug in (6,86000)

$A= a(b)^t\\A= 43000(b)^t\\86000=43000(b)^6\\2=b^6\\b=\sqrt[6]{2} \\b=1.12$

$A=43000(1.12)^t$

Now find out A when t=16 (2020)

$A=43000(1.12)^t\\A=43000(1.12)^{16}\\A=263606.9$
