Howe Industries sells on terms of 2/ 10, net 40. Gross sales last year were $ 4.5 million, and accounts receivable averaged $ 437,500. Half of Howe's customers paid on Day 10 and took discounts. What is the cost of trade credit to Howe's non-discount customers? ( Hint: Calculate sales per day based on a 360- day year, get the average receivables of discount customers, and then and the DSO for the non-discount customers.)
