Typical growth formulas are
P%28t%29=P%5B0%5D%281%2BG%29%5Et
where P%5B0%5D 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%28t%29=P%5B0%5D%281%2BG%29%5Et
P%284%29=7548000%281%2B0.039%29%5E4
P%284%29=7548000%281.1654%29
P%284%29=8796179
