Maximize p = 15x + 12y subject to the constraints: 5x + 4y 20 x, y 0. The maximum is : (a) 10. (b) 20. (c) 40. (d) 60. (e) none of the above. [3a] find the value of the pivot element in the following simplex tableau: 4 (a) 3. (b) -2. (c) 2. (d) -1. (e) 5. Maximize p = 2x + 3y + 2z subject to the constraints: 2x + y + 2z 26 x + y 3z 16 x, y, z 0. [4a] the maximum is: (a) 5. (b) 15. (c) 24. (d) 70. (e) none of the above. Minimize c = 10x + 14y 2z subject to the constraints: 2x + y + z 2 x, y, z 0. [6a] the minimum is: (a) -5. (b) -10. (c) 5. (d) 10. (e) none of the above. For the next two problems consider the following linear programming problem:
