A major supermarket chain, Rightway, has recently opened a new store in a newly redeveloped shopping mall. The main competing supermarket chain, WellMark, already had an outlet in the same mall.

The shopping mall is essentially a duopoly. The most obvious determinant is the price you charge and the price charged by your direct competitor. Chris knows this and has been monitoring price movements both of Rightway and of the competition. He has the price of a typical basket of meat products at Rightway for each week, measured in $/kg, as well as the price of the same basket of goods for WellMark.
