You are choosing between three classes to complete your requirements for general education credits. Class A meets from 2:30-4:00 PM on T, Th. The required text costs $130. Class B meets at the same time as Class A but its text costs only $30. Class C meets at 6-9 PM on Mondays and the required text costs $95. All three classes appear to be equally interesting and have similar reputations for how much work they need to get a grade of "A." Adding any of the three classes will increase your tuition payment by $1,200 for the semester.
Required:
a. Is the tuition of $1,200 relevant for your decision about which class to enroll in?
b. Why would most students prefer Class B to Class A?
c. Why is the time of the class relevant for the decision to choose between Classes A and
C but not relevant for the decision to choose between classes A and B? Is the meeting time relevant for the overall decision of which class to choose?
