Mako Industries is considering changes in its working capital policies to improve its cash flow cycle. Mako's sales last year were $5.5 million (all on credit), and its net profit margin was 6%. Its inventory turnover was 7.0 times during the year, and its DSO was 45 days. Its annual cost of goods sold was $3.85 million. The firm had fixed assets totaling $725,000. Mako's payables deferral period is 50 days. Suppose Mako's managers believe the annual inventory turnover can be raised to 9 times without affecting sale or profit margins. What would Mako's ROA have been if the inventory turnover had been 9 for the year? 17.87% 21.25% 18.02% 19.59%
