A = P+PRT for R

R=

To find the value of R in the equation A = P + PRT, we need to isolate R on one side of the equation. Here's how we can do that:

A = P + PRT

First, let's factor out R on the right side of the equation:

A = P(1 + RT)

Next, we'll subtract P from both sides to move it to the left side of the equation:

A - P = P(1 + RT) - P

A - P = P + PRT - P

Simplifying further:

A - P = PRT

Now, divide both sides of the equation by PT:

(A - P) / PT = R

Therefore, the value of R in the equation A = P + PRT is:

R = (A - P) / PT
