Solve for the indicated variable.
-A = P(1 + nr), for r

Question

Quizplus · Accepted Answer

To solve for r, we want to isolate the variable r on one side of the equation.

First, distribute the P and nr terms:

A = P + Pnr

Next, subtract P from both sides:

A - P = Pnr

Finally, divide both sides by Pn:

(A - P) / (Pn) = r

Therefore, the final equation for r is:

r = (A - P) / (Pn) Start by dividing both sides of the equation by P:

A/P = 1 + nr

Next, subtract 1 from both sides:

A/P - 1 = nr

Finally, divide both sides by n:

(A/P - 1)/n = r

So the solution for r is (A/P - 1)/n. This matches option C.
