Inventory was turned over 12 times during the year, and the DSO was 42 days. The firm had negligible amounts of cash and marketable securities, and it's fixed assets were $150,000. AFC's payables deferral period is 35 days. (a) Calculate AFC's cash conversion cycle. (b) Calculate AFC's total assets turnover and return on assets (ROA).
