Like a good economist, you calculated the full cost of getting your college degree. Suppose that at your university, you will pay $15,000 each year for tuition, $2,000 each year for textbooks, and $10,000 per year for room and board. Before you left for college, your boss at your high-school job offered you a job paying $20,000 per year. Assume that if you decided not to go to college, your parents would not let you live at home. What is your full cost for four years of college

Suppose that a candy maker owns a building and is renting part of the building's space to a doctor. further suppose that because the candy maker is the owner, he has the right to make noise during the day while he makes candy. while the doctor cannot insist on a quiet environment, the doctor could move to a quieter building. however, rent in the next best building is $350/month more than rent in the noisy building. the candy maker can adopt a new technology that eliminates the noise for $275/month. given this situation, can the doctor find a private solution with the candy maker that will make both better off?
