Have a couple questions I need some clarification on

^need C for this one

^need b for this one

Kalyan Singhal Corp. makes three products, and it has three machines available as resources as given in the following LP problem: Maximizecontribution=4X1+4X2+7X31X1+7X2+4X3802X1+1X2+7X3848X1+4X2+1X380X1,X2,X30(C1:hoursonmachine1)(C2:hoursonmachine2)(C3:hoursonmachine3) a) Using a computer software for solving LP, the optimal solution achieved is: X1=6.26 (round your response to two decimal places). X2=5.12 (round your response to two decimal places). X3=9.48 (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 available at the optimal solution (round your response to two decimal places). Machine 2 has hours of unused time available at the optimal solution (round your response to two decimal places). Machine 3 has hours of unused time available at the optimal solution (round your response to two decimal places). c) An additional hour of time available for third machine, is worth dollars to the firm (round your response to two decimal plac Each high school has a capacity of 900 students. You have been asked to develop a linear programming model so as to minimize the total number of student miles traveled by bus. Decision variable Xij : Number of students living in sector i traveling to school located in sector j. The number of decision variables for the model =15. a) The nhientive function for the I P marlel = b) Using a computer software for solving LP, the objective value at the optimal solution achieved is: Minimum number of total miles traveled (objective value) = (round your response to a whole number)
