Working with chemists at Virginia Tech and George Washington Universities, landscape contractor Kenneth Golding blended his own fertilizer, called “Golding Grow.” It consist of four chemical compounds, C-30, C-92, D-21, and E-11. The cost per pound for each compound is indicted as follows: Chemical cost per pound C-30 0.12 C-92 0.09 D-21 0.11 E-11 0.04 The specifications for Golding – Grow are as follows: (1) E-11 most constitute 15% of the blend (2) C-92 and C-30 must together constitute 45% of the blend (3) D-21 and C-92 can together constitute no more than 30% of the blend (4) Golding Grow is packaged and sold in 50-pound bags (A) Formulate an LP problem to determine what blend of the four chemicals will allow Golding to minimize the cost of a 50-pound bag of the fertilizer. (B) Solve using a computer to find the best solution.
