pls help with the incorrect ones which are shown and the last one, C. computing the maximum contribution margin given the optimal mix

Product Mox Decision, Single and Multiple Constraints, Basicis of Linear Proprarning different settings. For the corning penod, 200,000 machine hours are avalable, Manspement is trying to decide on the quantities of each product to produce. The following data are available: Required: 1. Determine the unuts of each product that should be produced in order to maximize profits. If a prodlact should not be produced at all, enter " 0 " as your answer. Cornflakes x units Brontiakes units 2. Decause of market conditions, the company can sell no more than 150,000 boxes of cornflakes and 300,000 boxes of branflakes. Do the following: a. Formulate the problem as o linear programming problem, If required, round your answers to the nearest cent. If a value is zero, enter " 0 " as your answer. Let X= Number of boxes of cornflakes Let Y - Number of boxes of branftakes Objectrve function: sibject to: Machine constraint: Demand constrant: Demand constraint: b. Select the optimal mix graph. (Units are in thousands) c. Compute the maximum contribition margin given the optimal mux
