Question
After completing their wedding ceremony, many of the newly married couples proceed to Fo-
tomemories, a photographer's studio conveniently located next door the Bovineville court house.
Information for the first four couples to visit Fotomemories appear in the table below. The time be-
tween their successive arrivals to Fotomemories (starting from its opening) and the time for taking
their photos are as follows:
Couple
1
23 H
4
Interarrival time
Service time
to Fotomemories (minutes) at Fotomemories (in minutes)
1
3
3
2
2
221
Upon having their photos taken, the couples pay for and receive their photos in a separate process.
Assume that no other couples were present when these couples were photographed and that each
is served in the order of their arrival. There is a single (very efficient!) photographer, so only one
couple can be photographed at a time. Others must wait in a waiting area outside the photographer's
wedding setup area. Note: Fotomemories' entire studio includes both the wedding setup and the
waiting area.
