please solve, I appreciate ur help!

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 +4X3 1X, +7X2 + 4xy s72 (C:hours on machine 1) 2X, +1X2 + 7X3 5 76 (Cy: hours on machine 2) 8X, +4X2 + 1X3 72 (Cy: hours on machine 3) X, X, X 20 s a) Using a computer software for solving LP, the optimal solution achieved is: X, - (round your response to two decimal places). X = 9.74 X = 6.44 ad Using a computer software for solving LP, the optimal solution achieved is: (response should be rounded to nearest 2nd decimal place) (response should be rounded to nearest 2nd decimal place) X3 = 16.30 (response should be roul sed to nearest 2nd decimal place) Contribution (objective value) = 155.84 (response should be rounded to nearest 2nd decimal place) of Machine 1 has 0.00 hours of unused time available at the optimal solution (response should be rounded to nearest 2nd decimal place) Machine 2 has 0.00 hours of unused time available at the optimal solution (response should be rounded to nearest 2nd decimal place) Machine 3 has 0.00 hours of unused time available at the optimal solution (response should be rounded to nearest 2nd decimal place) An additional hour of time available for third machine, is worth 0.64 dollars to the firm. (response should be rounded to nearest 2nd decimal place) Additional 6 hour of time available for second machine at no cost to the firm, are going to increase the obiective An additional hour of time available for third machine, is worth 0.64 dollars to the firm. (response should be rounded to nearest 2nd decimal place) Additional 6 hour of time available for second machine at no cost to the firm, are going to increase the ob value by dollars. (response should be rounded to nearest 2nd decimal place)
