4) Moulton Motors is advertising the following deal on a new Honda Civic: "Monthly payments of $400.40 for the next 60 months and this beauty can be yours!" The sticker price of the car is $18,000. If you bought the car, what interest rate would you be paying in both APR and EAR terms? What is the amortization schedule of the first six payments? 5) From 1991 to 2000, the U.S. economy had an annual inflation rate of around 2.90%. The historical annual nominal risk-free rate for this same period was around 5.31%. Using the approximate nominal interest rate equation and the true nominal interest rate equation, compute the real interest rate for that decade. 4) Moulton Motors is advertising the following deal on a new Honda Civic: "Monthly payments of $400.40 for the next 60 months and this beauty can be yours!"
