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 Howes customers paid on Day 10 and took discounts. What is the cost of trade credit to Howes nondiscount customers? (Hint: Calculate sales per day based on a 360-day year, get the average receivables of discount customers, and then find the DSO for the nondiscount customers.)
