Solving the formula for
To solve the formula for the time , follow these algebraic steps:
- Write the formula: .
- Isolate the term containing by subtracting from both sides: .
- Isolate by dividing both sides by : t = rac{A - P}{Pr}. This rearranged formula allows you to calculate the elapsed time when the final amount, principal, and interest rate are known.
