If someone offered to give you a $500,000 noninterest-bearing note that was due 5 years from today (you will receive only one $500,000 payment three years from today) how much would you loan them if you wanted to earn an 6% annual interest rate that is compounded semiannually?

Can you help me figure out the steps and answer to this problem?
