You just got closed out of an economics course you need to graduate and need to persuade the department chair to open another section. She tells you that the school will have to pay a part-time instructor $3,000 to teach the course, and that there will be an additional $50 in admin istrative costs per student to run the course. If tuition is $600 for the course, how many students would you need to sign up for the course to run?
