8 Given QM output on a product-mix problem as below: Objective: Maximize Results ---------- X1 X2 RHS Dual --------------------------------------------------------------------------------- Maximize 40 50 Material A 1 2 <= 40 16 Material B 4 3 <= 120 6 Material C 2 7 <= 300 0 --------------------------------------------------------------------------------- Solution 24 8 1,360 If one more unit of material B (in addition to 120) were obtained, how would the optimal objective function value, currently 1360, change? Increase by 16. Decrease by 16. Increase by 6. Decrease by 6. No change. We don't know until after re-solving the new linear program
