Let's calculate the monthly payment and the total interest paid for the mortgage using the **Finance** tab of a **TI-84 calculator**.

### Step 1: Gather the relevant inputs
- **Loan amount (PV)**: $175,000
- **Annual interest rate (APR)**: 7.7%
- **Loan term (N)**: 30 years
- **Number of payments per year**: 12 (monthly payments)

### Step 2: Break down the formula for monthly payment (PMT)

The formula for calculating monthly payment $PMT$ is:

\[
PMT = \frac{PV \cdot \frac{r}{12}}{1 - \left(1 + \frac{r}{12}\right)^{-12N}}
\]

Where:
- $PV$ = Present Value (loan amount)
- $r$ = annual interest rate (as a decimal)
- $N$ = loan term in years

### Plugging in the numbers:
- $PV = 175,000$
- $r = 0.077$
- $N = 30$

Let's calculate the monthly payment.The monthly payment needed to amortize the $175,000 mortgage loan over 30 years at an annual interest rate of 7.7%, compounded monthly, is approximately **$1,247.68**.

### Step 3: Calculate the total interest paid on the loan

The total interest paid can be found using:

\[
\text{Total Interest} = (\text{Monthly Payment} \times \text{Total Number of Payments}) - \text{Loan Amount}
\]

Let's calculate the total interest paid.The total interest paid over the life of the loan is approximately **$274,164.91**.

### Summary:
- **Monthly payment**: $1,247.68
- **Total interest paid**: $274,164.91
