Chastain Corporation is trying to determine the effect of its inventory turnover ratio and days sales outstanding (DSO) on its cash conversion cycle. Chastain's 2018 sales (all on credit) were $253,000; its cost of goods sold is 80% of sales; and it earned a net profit of 7%, or $17,710. It turned over its inventory 7 times during the year, and its DSO was 34.5 days. The firm had fixed assets totaling $43,000. Chastain's payables deferral period is 50 days. Assume 365 days in year for your calculations.
