Problem 2. Mortgage - Effective Annual Rate You have just purchased a home by borrowing $400,000 for 30-years at a fixed APR of 3.87%. The loan payments are monthly and interest is compounded monthly. What is the effective annual rate on the loan? (l.e., what is the interest rate once we take into account compounding?) *Make sure to input all percentage answers as numeric values without symbols, and use four decimal places of precision. For example, if the answer is 6%, then enter 0.0600.
