Use the formula for the present value of an ordinary annuity or the amortization formula to solve the following problem.
Please post the complete problem. As it is there is not enough information, as you have not told us how many times the interest compounds in a year.
Am I correct in assuming that "i" is the annual interest rate?
Well then it can not be solved. You need to know how many times the interest compounds in a year, so that you can calculate the necessary interest rate and the number of times the interest compounds in total.
