Problem: A school cafeteria can make pizza for approximately $0.40 per slice. The cost of the kitchen use and cafeteria staff runs about $200 per day. The Pizza Den nearby will deliver whole pizzas for $11 each. The cafeteria staff cuts their pizza into eight (8) pieces and serves them in the usual cafeteria line. With no cooking duties, the staff can be reduced by half, for a fixed cost of $79 per day.
