costumers arrive at the theater line at the rate of 75 per hour. the ticket seller averages 40 seconds per costumer, which included placing validation stamps on costuemrs parking lot recipts and punching their frequent watcher cards ( bc of these added services many costumers dont get in until after the feature has started)
what is the avg costumer time in the system ( round your answer to 2 decimal places)
what would be the effect on customer time in the system of having a second ticket taker doing nothing but validations and card punching, therby cutting the average service time to 25 seconds ( round your answer to 3 decimal places)
what would be the costumer time in the system if instead of change in part b a second window was opened with each server doing all three tasks?
