**How to Find Time in Compound Interest Word Problems?**

- Determine the principal amount \( P \), the desired final amount \( A \), the annual interest rate \( r \), and the number of times interest compounds per year \( n \).
- Use the formula `t = \frac{\log\left(\frac{A}{P}\right)}{n \cdot \log\left(1 + \frac{r}{n}\right)}` to calculate the time \( t \) required to reach \( A \) from \( P \) with compound interest.
- Plug in the known values into the formula step-by-step, ensuring to use of natural logarithms (logarithm base \( e \)).
- Understand the calculated time \( t \) in the context of the problem, indicating how long it will take for the investment or loan to grow to the desired amount \( A \).
