Consider the following LP problem. where x1 and x2 represent the decision variables. Solve the LP problem to answer the following questions. a. What are the values of x1 and x2 at the optimal solution? What is the maximum value of z ? Note: Round your answers to 2 decimal places. b. Identify the binding and nonbinding constraints and report the slack value, as applicable. Note: If the answer to constraints is "Non-Binding" enter slack value to 2 decimal places or leave cells blank. c. Report the shadow price and range of feasibility of each binding constraint. Note: If the answer to constraints is "Binding" enter the "Shadow price" and "Range of feasibility" to 2 decimal places or leave cells blank. d. What is the range of optimality for the two objective function coefficients? Note: Round your answers to 2 decimal places
