K The High Note Sound Company manufactures quality compact disc (CD) players and stereo receivers. Each of these products require a certain amount of skilled artisanship, of which there is a limited weekly supply. The firm formulates the following LP problem in order to determine the best production mix of CD players (X) and receivers (Y): Maximize profit = 50X + 120Y Subject to 2X + 4Y 80 (hours of electricians' time available) 3X + Y 60 (hours of audio technicians' time available) X, Y20 The following table provides the sensitivity report of the above formulation: Variable Cells Constraints Cell $C$3 $D$3 Cell $E$6 $E$7 Name CDPlayers Receivers Name Electrician Audio Technician Final Value 0 20 Final Value 80 20 Reduced Cost -10 0 The Shadow Price 30 Objective Allowable Allowable Coefficient Increase Decrease 1E+30 20 0 50 120 Constraint R.H.
