Answer 1

Certainly! Below is the correct representation of the Compound Interest Formula along with its components:

### COMPOUND INTEREST FORMULA

The formula for compound interest is given by:

\[
A = P\left(1 + \frac{r}{n}\right)^{nt}
\]

### Variable Meaning

- **A**: Amount of money in the account after \( t \) years.
- **P**: The original amount (in dollars) you put in the account (Principal).
- **r**: Interest rate (expressed as a decimal).
- **n**: Number of times interest is compounded per year.
- **t**: Number of years the money is invested or borrowed.

### Breakdown of the Formula

- The term \( \frac{r}{n} \) represents the interest rate per compounding period.
- The exponent \( nt \) represents the total number of compounding periods (n times per year for t years).

Make sure to carefully use this formula for calculating compound interest!
