Cullumber Company is able to currently sell all of the units that it can produce of either A132 or B345. If Unit A132 has a unit contribution margin of $60 and it takes three machine hours to produce and Unit B345 has a unit contribution margin of $48 and takes two machine hours to produce. If Cullumber Company has a constraint on machine hours, and currently has only 1950 machines of production time, which should Cullumber produce to maximize the operating income of the company? Make Unit B345 which creates $4 more profit per machine hour than Unit A132 does. The same total profits exist regardless of which product is made. Make Unit A132 which creates $12 more profit per unit than Unit B345 does. Make Unit B345 because more units can be made and sold than Unit A132
