Question
Suppose you sell Peppermint Bark and Biscochitos, each by the pound. Your profit function is given by P= 12x+6y-.002x^2-.01y^2 . Now, say you want to see what would happen if, at your current level of sales (25 lls of peppermint bark and 30 lbs of biscochitos) you added one more pound of peppermint bark. In other words, find the rate of change of sales with respect to peppermint bark when 25 lbs of bark and 30 lbs of biscochitos are sold. Now tell me what that means in the real world using complete sentences.
