Registration at Dalhousie University has always been a time of emotion, commotion, and lines. Students must move among four stations to complete the trying semiannual process. Last semester$$s registration, held in the fieldhouse, is described in Figure $9\mathrm{.}19.$ You can see, for example, that $450$ students moved from the paperwork station $($A$)$ to advising $($B$),$ and $550$ went directly from A to picking up their class cards $($C$).$ Graduate students, who for the most part had preregistered, proceeded directly from A to the station where registration is verified and payment collected $($D$).$ The layout used last semester is also shown in Figure $9\mathrm{.}19.$ The registrar is preparing to set up this semester$$s stations and is anticipating similar numbers.
