A 30,000-seat college football stadium is used 20 times for games, concerts, and graduation ceremonies. Each event averages four hours, and assume the stadium is full for each event. The stadium is available 365 days a year from 6 a.m. to midnight. Using Equation 7.1, find the stadium (seat) utilization. Can you think of one or two other assets that have such a low resource utilization? Utilization (U) = Resources Used/Resources Available
