Suppose one factory produces residential windows and doors. The following scenarios describe various​ straight-line production possibility boundaries for this factory. Each scenario describes the numbers of doors that could be produced in one day if all the​ factory's resources were devoted to producing doors and the number of windows that could be produced in one day if all the​ factory's resources were devoted to producing windows. For each​ scenario, calculate the opportunity cost to the factory owner of producing one extra door.
