Kalyan Singhal Corp, makes three products, and it has three machines available as resources as given in the following LP problem Maximize contribution 6X, +8X2 + 4X 1X, +7X2 + 4xy s72 (G: hours on machine 13 2X, + 1X2 +7X3 5 76 (Cz; hours on machine 2) 8X: +4X2 + 1X, 72 (Cg hours on machine 3) X1, X2, X, 20 a) Using a computer software for solving LP the optimal solution achieved is. Xx=(round your response to two decimal places) X = (round your response to two decimal places), (round your response to two decimal places) Contribution (objective value) =(round your response to two decimal places) b) Machine 1 has hours of unused time aynilable at the optimal solution (round your response to wo decimal places) Machine 2 hos hours of unused timo availablo at the optimol solution fround your response to two decimal places) Machine 3 hos hours of unused timo available at the optimal solution (round your response to two decimal places). c) An additional hour of time avilable for third machine, is worth dollars to the firm (round your response to two decimal places) d) An additional 5 hours of time available for the second machine, at no cost to the firm are going to increase the objective value by dollars fround your response to two decimal places).
