I do not understand this question is it ok if i have lots of details to make sure i undertand

2. INTERPRETATION OF COMPUTER OUTPUT Deegan Industries manufactures two types of roll bars for Porsches: Model DRB and Model DRW. . Model DRB requires 20 pounds of a special high alloy steel, 40 minutes of manufacturing time, and 60 minutes of assembly time. . Model DRW requires 25 pounds of the special high alloy steel, 100 minutes of manufacturing time, and 40 minutes of assembly time. Deegan's steel supplier indicated that at most 40,000 pounds of the high-alloy steel will be available next quarter. In addition, Deegan estimates that 2000 hours of manufacturing time and 1600 hours of assembly time will be available next quarter. The profit contributions are $200 per unit for Model DRB, and $280 for Model DRW. The computer solution for Deegan industries optimization problem is shown below a. Interpret the optimal solution and total profit contribution? (1 marks) b. The dual price of constraint is 8.80. What does it mean? (1 marks) c. Constraint 3 has a slack of 4000. What does it mean? (1 marks) Interpret the allowable increase and decrease in the objective function icient of DRB. (1 marks) c. If the available manufacturing time is increased by 500 hours, will the dual value for 1 the manufacturing time constraint change? Explain.
