Cost of Bank Loan Mary Jones recently obtained an equipment loan from a local bank. The loan is for $21,000 with a nominal interest rate of 13%. However, this is an installment loan, so the bank also charges add-on interest. Mary must make monthly payments on the loan, and the loan is to be repaid in 1 year. What is the effective annual rate on the loan (assuming a 365-day year)? Do not round intermediate calculations. Round your answer to two decimal places.
