From this data, as well as the data given on manufacturing methods and hours per method, a solution could be found utilizing the linear programming method of analysis. To analyze the data, the actual profit on each material was first calculated. This was done by taking the selling price and subtracting each cost associated with the given material. The results are $34.00 for the 75C, $30.00 for the 33C, $60.00 for the 5X, and $25.00 for the 7X. The next step was to determine how many constraints would be part of the analysis. There was determined to be 10 constraints in the analysis, 4 for the April orders, 4 for the manufacturing methods and 2 for the minimum orders promised by Vivian. With this data, the amount of each product to be produced to maximize profit for April could be determined. The results can be seen in Table 3.
