Exercise 6

Use the information in Table 1 (as well as the assumption about foregone income made in the chapter)to compare the opportunity cost of attending a year of college for a student at a two-year public college,under each of the following special assumptions:
a. The student receives free room and board at home at no opportunity cost to the parents.
b. The student receives an academic scholarship covering all tuition and fees (in the form of a grant,not a loan or a work-study aid).
c. The student works half-time while at school (assume for this problem that the leisure or study time sacrificed has no opportunity cost).
