Problem:
The ski season started in Mount Sunapee! Gerald Mitchell's ski and snowboard rental shop is located in the ski lodge area and offers a large selection of current snowboards, shaped skis, and helmets for children, women, and men. Gerald's winter rental shop is open every day that Mount Sunapee is open for skiing. The rental store maintains a current inventory of quality rental equipment with all rental equipment inventory replaced on a normal rotation basis every three to four years. Gerald Mitchell wants to understand better the factors that affect the demand for his ski and snowboard rental shop, so he can plan his capacity better. In particular, he wants to know how different factors, as the day of month, weekends, weather or school breaks affect their demand.
