Demand for a model ofSUV is given by the formula: 00:, y) : 31000 \E 1103.53, 10W2 where x is the price of the vehicle in dollars and y is the cost of gasoline per gallon, and the output D represents the number of cars demanded. Find the partial derivatives of the function when (x, y) = (60000, 5), and explain what they represent in words. Reference: Calculus: Early Transcendentals, Eighth Edition James Stewart
