31- Margetis Inc. carries an average inventory of $900,000. Its annual sales are $12 million, its cost of goods sold are 75% of annual sales, and its receivables collection period is twice as long as its inventory conversion period. The firm buys on terms of net 30 days, and it pays on time. Its new CFO wants to decrease the cash conversion cycle by 10 days, based on a 365-day year. He believes he can reduce the average inventory to $756,175 with no effect on sales. By how much must the firm also reduce its accounts receivable to meet its goal in the reduction of its cash conversion cycle? Do not round your intermediate calculations.
