A debt of $2,000 due 4 years from now is to be repaid by a payment of $1,000 now and a second payment at the end of 2 years. How much should the second payment be if the interest rate is 5% compounded annually? ps. my answer key says $711.56 but the last person who solved this got $1328.5125 and I'm not sure if it's correct. So I'm reposting the question.
