Compute the stated principal and constant monthly payments due on a 30-year mortgage that has an APR of 3.14% and that has 2.25 points but enables you to borrow $398,000+U dollars in cash (net of the points) in order to buy a house (which you have contracted to purchase for $498,000+U dollars using a $100,000 down payment).

Assume that you want to buy a house that costs $350,000+U dollars. If you make a 20% down payment, the APR is 4.88% on a 30-year mortgage. If you make a 10% down payment, the APR is 5.64% on a 30-year mortgage. Compute how much less you have to pay per month if you make the 20% down payment.

Compute how much a business is worth if it is expected to generate cash flows to its owners of $0 next year, $22,900 in two years, $34,800 in three years, then $54,000 per year for the subsequent U years (i.e., $54,000 per year after three years in the future and then continuing for the next U years until 3+U years into the future), and finally generates cash inflows to its owners of $75,000 per year thereafter forever (i.e., $75,000 forever after 3+U years), assuming that businesses with similar relevant risk have expected returns of 12%.

U = 13
