A market analyst has projected that the cost of producing d dog leashes will be given by the polynomial 10,500 + 3.9 d. The revenue generated from the sale of d dog leashes will be given by the polynomial d(14.5 – 0.00003 d). Find a polynomial expression for the profit earned from producing and selling d dog leashes. Evaluate the expression for d = 30,000.
