Question

The poultry farmer decided to make his own chicken scratch by combining alfalfa and corn in rail car quantities. A rail car of corn costs $400 and a rail car of alfalfa costs $200. The farmer's chickens have a minimum daily requirement of vitamin K (500 milligrams) and iron (400 milligrams), but it doesn't matter whether those elements come from corn, alfalfa, or some other grain. A unit of corn contains 150 milligrams of vitamin K and 75 milligrams of iron. A unit of alfalfa contains 250 milligrams of vitamin K and 50 milligrams of iron. Formulate the linear programming model for this situation.

 

Group of answer choices
Min Z = $450C + $200A Subject to: 150C + 250A ≥ 500 75C + 50A ≥ 400 C, A ≥ 0
Min Z = $400C + $200A Subject to: 150C + 250A ≥ 500 75C + 50A ≥ 400 C, A ≥ 0
Max Z = $400C + $500A Subject to: 150C + 250A ≥ 500 75C + 50A ≥ 400 C, A ≥ 0
Max Z = $400C + $200A Subject to: 150C + 250A ≥ 500 75C + 50A ≥ 400 C, A ≥ 0
Min Z = $400C + $200A Subject to: 150C + 250A ≥ 400 75C + 50A ≥ 500 C, A ≥ 0
Min Z = $400C + $200A Subject to: 150C + 250A ≥ 500 75C + 50A ≥ 400
