Answer:
her monthly payment = $725.78
Explanation:
The cost of Marissa's Home = $169,000.
Down-payment = 20% of the cost = 0.2 x 169000 = $33,800.
Loan Present Value, PV = $169000 - $33800 = $135,200.
Interest rate, R = 5%/12 = 1/240 = 0.004167
Tenure, N = 30 years = 30 x 12 = 360 months.
![Pmt = (PV*R)/([1-(1+R)^(-N) ]) \\\\Pmt = (135,200*0.004167)/([1-(1+0.004167)^(-360) ]) \\\\Pmt = \$725.78](https://img.qammunity.org/2019/formulas/mathematics/high-school/5u6g47qvon64e0ezvu3yqk0uhkk8efg2hp.png)
Hence, her monthly payment = $725.78
