For the following problems, you will need to write out the solution. You must show all work to receive credit. Each problem (or part of problem) shows the maximum point value. Provide at least four significant digits to each answer or you may not receive full credit for a correct solution.Show all work in order to receive credit. You will receive partial credit for incorrect solutions in some instances. Clearly circle your answer(s) or else you may not receive full credit for a complete and correct solution.

6. (8 points) Missy will be receiving a $100,000 loan from the Elliott Song National Bank today. The loan will last for 20 years, but the loan has a 25-year amortization schedule. (In other words, all payments will be made over the next 20 years, but the payment schedule will be made to mimic a 25-year payback for the loan.) The effective annual interest rate is 20%. The regular payments will be made yearly, starting one year from today. How much will the balloon payment have to be 20 years from today in order to completely pay back the loan?

7. (5 points) Mary has been hired to run a Fortune 500 company. Her first task is to figure out which of two mutually exclusive businesses should be located in a prime real estate location in Los Angeles, CA. Business 1 would require $1 million to be invested today, with $150,000 in revenue generated every year, starting one year from today. Business 2 would require $2 million to be invested today, with $250,000 in revenue generated every year, starting one year from today. If the effective annual interest rate is 9%, which business should Mary decide to invest in? (Note: Assume that any money not invested in one of these projects is invested with a net present value of zero.)
