Mako Industries is considering changes in its working capital policies to improve its cash flow cycle. Mako's sales last year were $6 million (all on credit), and its net profit margin was 10%. Its inventory turnover was 7.0 times during the year, and its DSO was 42 days. Its annual cost of goods sold was $4.2 million. The firm had fixed assets totaling $700,000. Mako's payables deferral period is 42 days. Assume Mako holds negligible amounts of cash and marketable securities, calculate its total asset turnover.
