9. In each of the following cases, explain whether you think the situation is efficient or not. If it is not efficient, why not?

What actions would make the situation efficient?

a. Electricity is included in the rent at your dorm. Some residents in your dorm leave lights, computers, and appliances on when they are not in their rooms.

b. Although they cost the same amount to prepare, the cafeteria in your dorm consistently provides too many dishes that diners don’t like, such as tofu casserole, and too few dishes that diners do like, such as roast turkey with dressing.

c. The enrollment for a particular course exceeds the spaces available. Some students who need to take this course to complete their major are unable to get a space even though others who are taking it as an elective do get a space.
