LP PROBLEM: Ozark Farms uses at least 800 lb. of special feed daily. The special feed is a mixture of corns and soybean meal with the following composition: per Ib. of feedstuff Feedstuff Protein Fiber Cost ($/lb.) Corn 0.09 0.02 0.30 Soybean meal 0.60 0.06 0.90 The dietary requirements of the special feed are at least 30% protein and at most 5% fiber. Ozark Farms wishes to determine the daily minimum-cost feed mix

Ozark Farms uses at least 800 lb. of special feed daily. The special feed is a mixture of corns and soybean meal with the following composition:
per Ib. of feedstuff
Feedstuff
Protein
Fiber
Cost ($/lb.)
Corn
0.09
0.02
0.30
Soybean meal
0.60
0.06
0.90
The dietary requirements of the special feed are at least 30% protein and at most 5% fiber. Ozark Farms wishes to determine the daily minimum-cost feed mix
1. Enter all the data from the problem into cells.
1. Data for corn, soybean meal and dietary requirements go in the G, H and I column respectively.
2. Data for protein go in G3 though 13
3. G4 through 14 are reserved for data about fiber.
4. The cost of corn per pound appears in cell G5 while the cost of soybean meal per pound appears in cell H5.
5. Merge the cell G7 and H7 (it contains the minimum daily special feed)
2. Set up the optimization model.
1. The cells G10 through H10 are reserved for values of the variables.
2. G12 contains a formula. It is the formula for the value of the objective function.
3. G15 through 115 contain the constraint for daily special feed
4. G16 through 116 contain the constraint for protein
5. G17 through 117 contain the constraint for fiber
