Use the following information to set up a linear programming model in Solver and use it to reach a solution. In the body of your post, be sure to write out the equations you used to build the model in addition to posting a solution. S&N Manufacturing makes four different steel sheets, A, B, C, and D, with different percentages of iron. Each sheet must flow through five departments, forming, rolling, sintering, painting, and quality check. The table below shows the relevant data. Production rates are shown in units/hour. (Sheet A uses imported steel and does not require rolling.) Sheet model Selling price Variable cost Min Sales Max Sales A $260.00 $220.00 0 4000 B $310.00 $250.00 0 3000 C $410.00 $310.00 500 2000 D $660.00 $530.00 500 1000 Production rates (units/hour) A B C D Hours Available (Monthly) Forming 50 40 20 20 330 Rolling - 30 20 20 330 Sintering 35 25 25 22 330 Painting 30 30 35 25 330 Quality check 60 50 50 40 330. S&N wants to determine the number of steel sheets to produce in order to maximize monthly profit. Let A, B, C, and D denote the number of units of model A, B, C, and D to be produced, respectively.
