Eli Daisy uses chemicals 1 and 2 to produce two drugs. Drug 1 must be at least 70% chemical 1, Drug 2 must be at least 60% chemical 2 but no more than 90% chemical 2 Up to 112 oz of Drug 1 can be sold at $6 per oz; up to 84 oz of Drug 2 can be sold at $5 per oz. Up to 126 oz of chemical 1 can be purchased at $6 per oz, and up to 112 oz of chemical 2 can be purchased at $4 per oz. Use the decision variables xij (i=1,2, j=1,2) to stand for number of oz of Chemical i that is added to Drug ] Use LPsolve or on-line solver to 1. the maximum possible profit is:
2. the value of x11 in optimal solution is :
3. the value of x12 in optimal solution is :
4. the amount of drug1 that is produced is:
