Answer both questions
To determine the regular payment amount, rounded to the nearest cent, use the formula:

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

The cost of a home is financed with a $100,000 40-year fixed-rate mortgage at 3%.

### Loan Payment Formula and Amortization Schedule

#### Loan Payment Calculation

To determine the regular payment amount for a fixed-rate mortgage, use the following formula:

\[
\text{PMT} = P \left( \frac{r}{n} \right) \div \left[ 1 - \left( 1 + \frac{r}{n} \right)^{-nt} \right]
\]

Where:
- \( P \) = Principal loan amount
- \( r \) = Annual interest rate
- \( n \) = Number of payments per year
- \( t \) = Loan term in years

For this scenario, a home is financed with a $100,000 40-year fixed-rate mortgage at 3%.

**Tasks:**
a. Calculate the monthly payments and total interest for the loan.
b. Prepare a loan amortization schedule for the first three months.

#### Amortization Schedule

Complete the amortization schedule for the first three months of the mortgage below:

| Payment Number | Interest | Principal | Loan Balance |
|----------------|----------|-----------|--------------|
| 1              | $        | $         | $            |
| 2              | $        | $         | $            |
| 3              | $        | $         | $            |

*(Use the answer from part a to find these answers. Round to the nearest cent as needed.)* 

This exercise will help you understand how your monthly payments affect both the interest and principal, as well as how the loan balance decreases over time.
