The Wisconsin Agricultural Extension Office Publishes Recommendations for Farmers

Short Answer

The Wisconsin Agricultural Extension office publishes recommendations for farmers. A recent publication stated that dairy cows should be fed corn (C) according to their production (P) of milk, with the minimum amount of corn being given by the equation C_min = 0.33P + 5 and the maximum amount of corn being C_max = 0.39P + 7. According to this recommendation, what would be the maximum amount of corn that should be fed to a cow that is producing 67 pounds of milk?
