The production of Star100 should be reduced as it has the lower contribution margin per hour.
Of 20000 direct labor hours, 12960 hours ((3600*1.6)+(3600*2))will be used for special order. Of remaining 7040, 4000 hours will be used to produce 2000 units of Star150 and then 3040 units will be used to produce 1900 units of Star100.
Contribution margin = price – variable costs
210-119 = 91
260-144=1166
