Employees in a factory arrive at the tool crib at an average rate of one employee every five minutes. There are two tool crib taking and 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?
