Based on 3.8 problem 7: Eli Daisy uses chemicals 1 and 2 to produce two drugs. Drug 1 must be at least 70% chemical 1, and Drug 2 must be at least 60% chemical 2. Up to 112 oz of Drug 1 can be sold at $8 per oz; up to 84 oz of Drug 2 can be sold at $6 per oz. Up to 126 oz of chemical 1 can be purchased at $5 per oz, and up to 110 oz of chemical 2 can be purchased at $4 per oz. Formulate an LP that can be used to maximize profits. Suggestion for one decision variable: x12 for oz of Chem1 in Drug 2 What is the (value of the) optimal profit? z = How much of Drug 1 will be produced? How much of Chemical 2 will be purchased?

Each emits two types of pollutants, labeled P1 and P2, into the river. If the waste from each factory is processed, the pollution in the river can be reduced. It costs $1500 to process a ton of factory 1 waste, and each ton processed reduces the amount of P1 by 0.10 ton and the amount of P2 by 0.45 ton. It costs $1000 to process a ton of factory 2 waste, and each ton processed reduces the amount of P1 by 0.20 ton and the amount of P2 by 0.25 ton. It costs $2000 to process a ton of factory 3 waste, and each ton processed reduces the amount of P1 by 0.40 ton and the amount of P2 by 0.30 ton. The state wants to reduce the amount of P 1in the river by at least 30 tons and the amount of P2 by at least 40 tons. Use Solver to determine how to minimize the cost of reducing pollution by the desired amounts. Use SolverTable to investigate the effects of increases in the minimal reductions required by the state.
