21. Dr. Rock takes out a loan for 100.000. The annual effective interest rate on the loan is 10%. Dr. Rock repays the loan by making payments at the end of each year. With the exception of the final payment, the payment amount is equal to three times the interest due. Dr. Rock's final payment is the balance due at that time, and the loan is arranged so that final payment does not exceed 1000. (a) How many payments does...
