Solve for the indicated variable p
I don't know what you do to solve it.
A=P+Prt

MathMate,
To solve for P in
A=P+Prt
you would arrange all terms containing P on the left, and everything else to the right, namely:
PPrt=A
Now factor using the distributive property:
(1+rt)P=A
Divide both sides by the coefficient of P:
P=A/(1+rt)
