LP2-2: a) Develop your own original LP problem with two constraints and two real variables. b) Explain the meaning of the numbers on the right-hand side of each of your constraints. Try to avoid a product mix example. c) Explain the significance of the technological coefficients. d) Solve your problem using QM for Windows to find the optimal solution. e) In your own words, describe what this solution means. f)) Using QM for Windows demonstrate the effect of increasing the contribution rate of your first variable (X1) by 50% over the value you first assigned it and discuss whether it changes the model's optimal solution? LP2-3: a) Using the model you developed in the previous example, describe the 5 ways LP models can change and give an example of why such a change would be needed for that specific model, b) Identify which of these changes would be appropriate for using the Range Table
