Alyeski Tours operates day tours of coastal glaciers in Alaska on its tour boat the Blue Glacier. Management identified two cost drivers for budgeting purposes$-$the number of cruises and the number of passengers. The company publishes a schedule of day cruises that it may supplement with special sailings if there is sufficient demand. Up to $82$ passengers can be accommodated on the tour boat.
