A=P(1+nr); find r
To find the value of r in the equation A = P(1 + nr), where A, P, and n are known variables, you can follow these steps:
Step 1: Start by isolating the term containing r on one side of the equation. Divide both sides of the equation by P:
A/P = 1 + nr
Step 2: Subtract 1 from both sides of the equation to isolate the term containing nr:
A/P - 1 = nr
Step 3: Divide both sides of the equation by n:
(A/P - 1) / n = r
So, by dividing (A/P - 1) by n, you can find the value of r in the equation A = P(1 + nr).
