The Outfront BBQ Rib Haven does carry out only. During peak periods, two servers are on duty. The owner notices that during these periods, the servers are almost never idle. She estimates the percent idle time of each server to be 1 percent. Ideally, the percent idle time would be 10 percent to allow time for important breaks.
(a) If the owner decides to add a third server during these times, how much idle time would each server have then?
(b) Suppose that by adding the third server, the pressure on the servers is reduced, so they can work more carefully, but their service output rate is reduced by 20 percent. What now is the percent time each would be idle?
(c) Suppose, instead, that the owner decides to hire an aid (at a much lower salary) who servers as a gofer for the two servers, rather than hiring another full server. This allows the two servers to decrease their average service time by 20 percent (relative to the original service times). What now is the percent idle time of each of the two servers?
