Agatha Concrete Company has been offered by its bank to manage its cash at a cost of $35,000 per year. Under the proposed cash management, the firm can reduce the cash required on hand by $180,000. Since the bank is also doing a lot of record keeping, the firm's administrative cost would decrease by $2,000 per month. What recommendation would you give the firm with respect to the proposed cash management assuming the firm's opportunity cost is 12 percent?
