BANA: Introduction to Quantitative AnalysisDukedom Chemicalsblends its private label orchard spray from four individual compounds. Management would like to make the blend at as low a cost as possible while maintaining the requirements for chemical structure. The following linear programming problem has been formulated and the computer solution to it is provided.xi= The number of units of compound i to put in the blend, i=1,...,4MIN Z = 25x1+ 36x2+ 16x3+ 4x4S.T.12x1+ 9x2+ 10x3+ 6x4780Units of Chemical 15x1+ 22x2+ 19x3+ 10.2x4900Units of Chemical 2x1, x2, x3, x40Microsoft Excel 9.0 Answer ReportWorksheet: [Book2]Sheet1Report Created: 5/8/2003 12:49:19 PMTarget Cell (Min)CellNameOriginal ValueFinal Value$B$18Total Cost Amount0520Adjustable CellsCellNameOriginal ValueFinal Value$A$11Compound 100$B$11Compound 200$C$11Compound 300$D$11Compound 40130ConstraintsCellNameCell ValueFormulaStatusSlack$B$15Chemical 1 Amount780$B$15>=$F$5Binding0$B$16Chemical 2 Amount1326$B$16>=$F$6Not Binding426
