Problem 2 A manager is planning to build a recycling plant. The fixed and variable costs for the three potential sites are as follows. a. Plot the total cost for each site in the same graph. b. Over what range of recycling volume is each site optimal? c. If the expected production volume is 10,000 tons, which site is best? 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 ploces. b. Identify the binding and nonbinding constraints and report the slack value, as applicable. Note: If the onswer to constraints is "Non-Binding" enter slack value to 2 decimal places or leave cells blank
