unstained models arc a linear program to determine what WBF should produce in order to maximize its holiday profits? Example 18 A company produces three products from raw material and the other products. Each pound of raw material undergoes processing and yields 3 ounces of product 1 and 1 ounce of product 2 . Each pound of raw material costs $25 to purchase and takes 2 hours of labor to process. Each ounce of product 1 can be handled in one of the three ways. First, it can be sold for $10 per ounce. Second, it can be processed into 2/3 ounce of product 2 . This requires 2 hours of labor and costs an additional $1. Third, it can be processed into 1/2 ounce of product 3 . This requires 3 hours of labor and costs an additional $2. Each ounce of product 2 can be used in one of the two ways. First, it can be sold for $20 per ounce. Second, it can be processed into 3/4 ounce of product 3 . This requires 1 hour of labor and costs $6 more. Product 3 is sold for $30 per ounce. The maximum numbers of ounces of products 1,2 , and 3 that can be sold are, respectively, 5000,4000 , and 3000 . A maximum of 25,000 hours of labor are available. Formulate and solve a linear program that allows the company to maximize their profit? P(i,j) denote the amount of product i processed into product j, Solder miticate the simetin: of Product i sold
