A U.S. Postal Service supervisor is looking for ways to reduce stress in the sorting department. With the existing arrangement stamped letters are machine-canceled and loaded into tubs with 350 letters per tub. The tubs are then pushed to postal clerks, who read and key zip codes into an automated sorting machine at the rate of one tub per 385 seconds. To overcome the stress caused when the stamp canceling machine outpaces the sorting clerks, a pull system is proposed. When the clerks are ready to process another tub of mail, they will pull the tub from the canceling machine area. How many tubs should circulate between the sorting clerks and the canceling machine if 95,000 letters are to be sorted during a 10 hour shift, the saftey stock policy variable, a, is 0.05, and the average waiting time plus material handling time is 15 minutes per tub.

The average processing time per tub of letters, p, is ___ day. (round four decimal places)

The average waiting time per tub of letters, w, is ___ day. (round four decimal places)

Therefore, the number of tubs that should circulate between the sorting clerks and the canceling machine is ___ tubs. (round to the nearest whole number)
