You are the manager of a local sporting goods store and recently purchased a shipment of $60$ sets of skis and ski bindings at a total cost of $$25,000($your wholesale supplier would not let you purchase the skis and bindings separately, nor would it let you purchase fewer than $60$ sets$).$ The community in which your store is located consists of many different types of skiers, ranging from advanced to beginners. From experience, you know that different skiers value skis and bindings differently. However, you cannot profitably price discriminate because you cannot prevent resale. There are about $20$ advanced skiers who value skis at $$400$ and ski bindings at $$275$; $20$ intermediate skiers who value skis at $$300$ and ski bindings at $$400$; and $20$ beginning skiers who value skis at $$200$ and ski bindings at $$350.$ Determine your optimal pricing strategy.
