Ingram Office Supplies, Inc., buys on terms of 2/15, net 50 days. It does not take discounts, and it typically pays on time, 50 days ofter the invoice date. Net purchases amount to $800,000 per year. On average, what is the dollar amount of COSTLY trade credit (total credit-free credit) the firm receives during the year? (Assume a 365-day year). Please show work so I can learn how to do it, thanks! :)
