Southeastern Oklahoma State University's business program has the facilities and faculty to handle an enrollment of 2,000 new students per semester. However, in an effort to limit class sizes to a "reasonable" level (under 200, generally), Southeastern's dean, Tom Choi; placed a celilng on enrollment of 1,800 new students. Although there was ample demand for business courses last semester, conflicting schedules allowed on 1,420 new students to take business courses. What is the utilization and efficiency rate for Southeastern?
