A town has a population of 8400 i 1990. Fifteen years later, it's population grew to 12500. Determine the average annual growth rate of this town's population.

I really don't understand this problem. I've been going at it for hours and all I've come to is that the equation should be P=8400(1+x)^15 x being the annual percentage, so then, I substitute 12500 for P. but I don't know where to go from there. Please, I really need help on this.
