c. Room and board

d.Tuition and fees

2. Excluding "other expenses" which cost category varies the least among the different types of institutions? Can you explain why this category varies so little?

A. Transportation varies the least because students at all types of colleges have the same mode of transportation.

B.Room and board varies the least because it costs all types of colleges the same amount of money to have a student live on campus.

C.Books and supplies varies the least because students at all types of colleges need approximately the same number of books and supplies and these don't vary much in cost.

D.Tuition and fees varies the least because the operational costs for all types of colleges are the same.

3. Ignoring the "other expenses" category, the general trend is for all categories to cost more as you look down the chart from two-year public colleges to four-year private colleges. However, one category is an exception to this trend. Which category? Can you explain why? (Hint: If more than one category appears to have a downward trend, focus on the category with the largest downward trend.)

A.Tuition and fees because two-year public colleges need to charge more to attend due to smaller enrollment numbers

B.Room and board because it costs less to live on-campus than to live-off campus

C.Books and supplies because two-year public colleges require more books and supplies than four-year private colleges

D.Transportation because commuters must spend more money to get to school than students living on-campus
