Question: Please note that this problem has ten parts (a' to "j'). . You may need to scroll the screen down, navigate left and right to see the whole problem. Clearly label your parts when answering. You are allowed a Maximum of 3 Files for this problem. Must use a pen to answer. Must Show all calculations/steps where required. Failure to do so will result in a score of "0" even final answer is correct. FOUR PLACES AFTER THE DECIMAL POINT (except when all succeeding digits are zeros). Consider the following LP: Min 5X + 7Y S.t. X + 5Y > 28 (Constraint # 1) ?X + ?Y = 26 (Constraint # 2) X + 2Y = 17 (Constraint # 3) 2X - Y21 (Constraint # 4) X20, Y 20 (Non- Negativity constraints) Microsoft Excel: Sensitivity Report Variable Cells Final Reduced Objective Allowable Allowable Cell Name Value Cost Coefficient Increase Decrease $B$14 Values X 3 [a] 5 1E+30 3.6 $C$14 Values Y 5 7 [b] [c] Constraints Final Shadow Constraint Allowable Allowable Cell Name Value Price R.H.

(9) What is the objective function value? (h) Which constraint/s is/are binding? (0) Suppose the coefficient of variable X is decreased to $1.5. Is the above solution still optimal? If it is, then state the revised value of the objective function. If it is not, then give reasoning? () If the right-hand side of constraint #1 increased by 7. Is the above solution still optimal? If it is, then state the revised value of the objective function. If it is not, then give reasoning
