=+The head of the enrolment advisers at the university has decided that the advisers must finish their advising in two weeks and therefore must advise 420 students a day. However, the average waiting time given a 12-minute advising period will result in student complaints, as will reducing the average advising time to 10 minutes. Sturdy University is considering two alternatives:

A Hire two more advisers for the two-week (10-working day) advising period. This will increase the available number of advisers to 12 and therefore lower the average waiting time.

B Increase the number of days that the advisers will work during the two-week registration period to six days a week. If Sturdy University increases the number of days worked to six per week, then the 10 advisers need only see 350 students a day to advise all of the students in two weeks.

Required 1 What would the average wait time be under each alternative described above?
