To rearrange the formula \( A = P + Prt \) to solve for \( r \), you would want to isolate \( r \) on one side of the equation.
The best first step is to **subtract \( P \) from both sides of the equation**. This gives you:
\[ A - P = Prt \]
From there, you could divide both sides by \( Pt \) to solve for \( r \), but the first step, as you asked, would indeed be to subtract \( P \) from both sides.
So the correct option is:
**Subtract P from both sides of the equation.**
