Duncan Brooks needs to borrow $500,000 to open new stores. Brooks can borrow $500,000 by issuing 5%, 10-year bonds at 96. How much will Brooks actually receive in cash under this arrangement? How much must Brooks pay back at maturity? How will Brooks account for the difference between the cash received on the issue date and the amount paid back?

I do not understand how to answer this question and the one answer I found for this question is not in detail and did not help me!
