The computer solution is shown below. The computer solution is shown below. Ontimal Ohiertive Valine =19580.00000 (a) Identify the range of optimality for each objective function coefficient. (If there is no upper or lower limit, enter NO LIMIT.) (c) Identify the range of feasibility for the right-hand-side values. (If there is no upper or lower limit, enter NO LIMIT.) constraint 1 to constraint 2 to constraint 3 to (d) If the number of fan motors available for production is increased by 60, will the dual value for that constraint change? Explain. Yes, the dual value will change because 60 is greater than the allowable increase of 12 . Yes, the dual value will change because 60 is greater than the allowable increase of 30 . No, the dual value will not change because 60 is less than the allowable increase of 290 . No, the dual value will not change because there is no upper limit to how much the constraint can increase
