There are three factories upon the Ohio River (A, B, C). Each and every emits two kinds of pollutants (1 and 2) in the river. If the waste from each factory is processed, the pollution in river can be reduced. It costs $1500 to process a ton of factory A waste, and each ton processed reduces the amount of pollutant 1 by 0.10 ton and amount of pollutant 2 by 0.45 ton. It costs $1000 to process a ton of factory B waste, and each ton processed will reduce amount of pollutant 1 by 0.20 ton and the amount of pollutant 2 by 0.25 ton. It costs $2000 to process a ton of factory C waste, and each ton processed will reduce the amount of pollutant 1 by 0.40 ton and the amount of pollutant 2 by 0.30 ton. The state wants to reduce the amount of pollutant 1 in the river by at least 30 tons and amount of pollutant 2 in the river by at least 40 tons.
A. Clearly show the model setup for this in excel
B. Describes steps necessary to use solver to determine how to minimize the cost of reducing pollution by the desired amounts.
