Computer Classes

Commenticius University is building a new technology building and wants to know how many computer classrooms it needs to plan for in the construction. The university offers classes on three different class schedules: Monday-Wednesday-Friday (MWF), TuesThursday (TR) or Saturday. On the MWF schedule there are 9 class periods during the day and 2 evening periods. On the TR schedule, there are 6 day class periods and 2 evening periods. On Saturday, there are only 2 day periods. The Computer Technology Department only has 2 faculty who teach in the evenings and 5 that can teach on Saturdays. If the Computer Technology Department wishes to offer 54 computer classes on the MWF schedule, 45 classes on the TR schedule and 10 on the Saturday schedule, what is the minimum number or computer classrooms needed to accommodate all of the computer classes in the new building?
