Problem Statement
The Holiday Meal Turkey Ranch is considering buying two different brands of turkey feed and blending them to provide a good, low-cost diet for its turkeys. Each feed contains, in varying proportions, some or all of the three nutritional ingredients essential for fattening turkeys. Each pound of brand 1 purchased, for example, contains 5 ounces of ingredient A, 4 ounces of ingredient B, and 0.5 ounce of ingredient C. Each pound of brand 2 contains 10 ounces of ingredient A, 3 ounces of ingredient B, but no ingredient C. The brand 1 feed costs the ranch $0.02 per pound, while brand 2 feed costs $0.03 per pound. Determine the lowest-cost diet that meets the minimum monthly intake requirement for each nutritional ingredient.
Table 1.
Product Resource Requirements
Ingredient	Brand 1 Feed (B1)	Brand 2 Feed (B2)	Min Monthly Requirement per Turkey Oz
A	5	10	90
B	4	3	48
C	0.5	0	1.5
Cost per pound	$0.02	$0.03
LP Model Formulation Steps
1. Define the decision variables - one variable per row. Format: Variable label = Variable name
2. Define the objective function - Format: Max/Min = equation using variable labels and values
3. Define the constraints - one constraint per row. Provide a title for the constraint. Format = Title: equation
