Suppose that the profit (In dollars) from the sale of Kisses and Kreams is given by P(x, y) = 15x + 6.5y – 0.004x2 – 0.015y2 where x is the number of pounds of Kisses and y is the number of pounds of Kreams. Find aP/dy, and give the approximate rate of change of profit with respect to the number of pounds of Kreams that are sold if 100 pounds of Kisses and 19 pounds of Kreams are currently being sold. (Give an exact answer. Do not round.) $ What does this mean? If the number of pounds of Kisses is held constant and the number of pounds of Kreams is increased from 19 to 20, the profit will increase by approximately $
