The Ozark Farm has 20,000 broilers that are fed for 8 weeks before being marketed. The weekly feed per broiler varies according to the following schedule:

For the broiler to reach a desired weight gain in 8 weeks, the feedstuffs must satisfy specific nutritional needs. Although a typical list of feedstuffs is large, for simplicity we will limit the model to three items only: limestone, corn, and soybean meal. The nutritional needs will also be limited to three types: calcium, protein, and fiber. The following table summarizes the nutritive content of the selected ingredients together with the cost data.

The feed mix must contain
(a) At least .8% but not more than 1.2% calcium
(b) At least 22% protein
(c) At most 5% crude fiber
Solve the LP for week 1 and then use post-optimal analysis to develop an optimal. Schedule for the remaining 7 weeks.
