Kalyan Singhal Corp. makes three products, and it has three machines available as resources as given in the following LP problem: Maximizecontribution=1X1+7X2+4X31004X1+4X2+7X32X1+1X2+7X31108X1+4X2+1X3100X1,X2,X30(C:hoursonmachine1)(CC2hoursonmachine2)(CC3:hoursonmachine3) a) Using a computer software for solving LP, the optimal solution achieved is: X1=(roundyourresponsetotwodecimalplaces). a) Using a computer software for solving LP, the optimal solution achleved is: X1= (round your response to two decimal places). x2= (round your response to two docimal places). X3= (round your rosponse to two docimal places). Contribution (objective value) = (round your response to two decimal places). b) Machine 1 has hours of unused time avallable at the optimal solution (round your response to fwo decimal places). Machine 2 has hours of unused time avallable at the optimal solution (round your rosponse to two decimal places). Machine 3 has hours of unused time avalable at the optimal solution (round your rosponse to two docimal paces). c) An additional hour of time avallable for third machine, is worth dollars to the firm (round your response to mo docimal places). Use sensitivity table to answor this questions. d) An additional 10 hours of time available for the second machine, at no cost to the firm, are golng to increase the objective value by dollars (round your response to three decimal places). Use sensitivity table to answer this questions
