Consider the Following Integer Linear Programming Problem

Short Answer

Consider the following integer linear programming problem:
Max Z =   3x1 + 2x2
Subject to:  3x1 + 5x2 ? 30
      5x1 + 2x2 ? 28
        x1 ? 8
       x1, x2 ? 0 and integer
The solution to the linear programming formulation is: x1 = 5.714, x2 = 2.571.
What is the optimal solution to the integer linear programming problem?
State the optimal values of decision variables and the value of the objective function.
