Harrington Corporation produces three products, A, B, and C. Pertinent information on these products is as follows: Product Selling Price per Unit Variable Cost per Unit Fixed Cost per Unit DL Hours per Unit A (Anchor bolts) $4.00 $1.00 $2.00 2 B (Bearings) $3.50 $0.50 $2.00 2 C (Castings) $6.00 $2.00 $3.00 3 There are 150 direct labor hours available. Machine-hour capacity allows 100 anchor bolts, only; 50 bearings, only; 40 casters, only; or any combination of the three that does not exceed the capacity. The direct labor hour constraint for Harrington's linear programming model is:a. A + B + C ≤ 150.b. Min Z = 2A + 2B + 3C. c. Max Z = 2A + 2B + 3C - 150.d. 100A + 50B + 40C ≤ 1,050.e. 2A + 2B + 3C ≤ 150.
