Final answer:
To solve for r in the formula A=P+Prt, we can isolate r. By subtracting P from both sides of the equation and dividing by Pt, we can find the solution for r.
Step-by-step explanation:
To solve equations for r in the formula A=P+Prt, we can first isolate r on one side of the equation. Here's how:
- Subtract P from both sides of the equation: A - P = Prt
- Divide both sides of the equation by Pt: (A - P)/(Pt) = r
So, the solution for r is (A - P)/(Pt).
