SENSITIVITY ANALYSIS 1. Given: Objective Function: Min z = 6x1 + 9x2 ($ cost) Subject to: X1 + 2X2 8 10X1 + 7.5X2 30 X2 2 X1, X2 0

a) Solve graphically then find the Optimal Solution. solve the optimal values using excel solver b) Determine the shadow prices. c) Suppose the unit cost of x1 is decreased to $4. Is the current solution still optimal? What is the value of the objective function when this unit cost is decreased to $4?

d) How much can the unit cost of x2 be decreased without concern for the optimal solution changing? e) What are the Ranges for the RHS value of the binding constraints?
