Employees in a factory arrive at the tool crib at an average rate of one employee every five minutes. There are two cool crib clerks taking and filling employee's orders. The average time for a tool room clerk to fill an employee's request is six minutes. Assume that management has valued employee's waiting time at $18 per hour to reflect the cost of lost productivity. The cost for each clerk is $6 per hour. In addition, the two computers used by the clerks are rented at a cost of $20 each per day. If the tool room is open for business 9 hours per day, what is the daily cost of this operation?
