Solve the formula for R. A=P+PRT
To solve for R in the formula A=P+PRT, you can follow these steps:
1. First, group the terms that contain R together.
A = P + PRT
A = P(1 + RT)
2. Divide both sides by P to isolate the term with R on one side.
A/P = 1 + RT
3. Subtract 1 from both sides.
A/P - 1 = RT
4. Divide both sides by T to solve for R.
R = (A/P - 1) / T
Therefore, the formula for R is R = (A/P - 1) / T.
