Question 335046: A=P(1+rt) for r

You can put this solution on YOUR website! I decide to answer this question a second time providing more steps.
A = P(1+rt) solve for r.
To solve for a variable means to isolate the variable. We want little r alone on right side of the equation.
We first apply the distributive law on the right side. We apply this law to remove the parentheses.
After applying the distributive law, we get A = P + Prt.
We now subtract P from A on the left side.
This is what the equation looks like now: A - P = Prt
On the right side, we have P*r*t or simply Prt.
To finally isolate little r, divide both sides of the equation by Pt.
Final answer: (A - P)/Pt = r
This is called literal equations not linear equations.
Understand?
