Solve these problems using graphical linear programming and then answer the questions that follow. Use simultaneous equations to determine the optimal values of the decision variables. 1. What are the optimal values of the decision variables and Z ? (Round your answers to 1 decimal place.) 2. Do any constraints have (nonzero) slack? If yes, which one(s) and how much slack does each have? None of the constraints have any slack. The first constraint has a slack of 10. The second constraint has a slack of 15. 3. Do any constraints have (nonzero) surplus? If yes, which one(s) and how much surplus does each have? The third and fourth constraints have surpluses of 92 grams and 10 grams respectively. The first and third constraints have surpluses of 90 grams and 10 grams respectively. The fourth and first constraints have surpluses of 94 grams and 20 grams respectively. 4. Are any constraints redundant? If yes, which one(s)? Yes, the third constraint is redundant. Yes, the second constraint is redundant. Yes, the first constraint is redundant. b.
