A=P%2BPrt Start with the given equation.


A=P%281%2Brt%29 Factor out the GCF "P".


A%2FP=1%2Brt Divide both sides by "P".


A%2FP-1=rt Subtract 1 from both sides.


A%2FP-P%2FP=rt Rewrite "1" as P%2FP.


%28A-P%29%2FP=rt Combine the fractions.


%28A-P%29%2F%28Pt%29=r Divide both sides by "t" to isolate "r".


So the answer is r=%28A-P%29%2F%28Pt%29
