Can anyone help me with this question?

Question

1. You’ve opened a clothing store and made a deal with a hat manufacturer to supply you with hats to sell along with your clothing.  The first shipment of hats will cost you $5,000.  When the hats are delivered, the supplier gives you an invoice that reads “5/15 n60” on the top. How much of a discount is the supplier giving you, in dollars?  How long do you have to pay the supplier to receive that discount?  If you don’t get the discount, how long do you have to pay back the $5,000?

Answer 1

You get a 15% discount if you pay within 15 days.

The total amount is due within 60 days of receipt.
