Based on Boykin (1985). Chemco annually produces 359 million pounds of the chemical maleic anhydride. A total of four reactors are available to produce maleic anhydride. Each reactor can be run on one of three settings. The cost (in thousands of dollars) and pounds produced (in millions) annually for each reactor and each setting are given in the file P06_69.xlsx. A reactor can be run on only one setting for the entire year. Determine how Chemco can minimize the cost of meeting its annual demand for maleic anhydride.
