Implement the following LP problem in a spreadsheet. Use Solver to solve the problem and create a Sensitivity Report. Use this information to answer the following questions: What range of values can the objective function coefficient for variable assume without changing the optimal solution? Is the optimal solution to this problem unique, or are there alternate optimal solutions? How much does the objective function coefficient for variable have to increase before it enters the optimal solution at a strictly positive level? What is the optimal objective function value if equals 1? What is the optimal objective function value if the RHS value for the second constraint changes from 15 to 25? Is the current solution still optimal if the coefficient for in the second constraint changes from 5 to 1? Explain.
