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.

divide both sides by 8400

1.488=(1+x)^15

take the fifteenth root of each side

1.488^(1/15)=1+x

1.027=1+x
