Question 147005
Typical growth formulas are
{{{P(t)=P[0](1+G)^t}}}
where {{{P[0]}}} is the initial population at time t=0, 
G is the rate of growth given in percent (change to decimal for calculation),
t is the time(work hand in hand with growth rate, years in this case). 
In your case, the year 2008 would be t=0, then 2012 would be t=4, 
4 years from the inital population.
{{{P(t)=P[0](1+G)^t}}}
{{{P(4)=7548000(1+0.039)^4}}}
{{{P(4)=7548000(1.1654)}}}
{{{P(4)=8796179}}}
