The price of a certain item is given by the equation p= 240 – 0.05x where x is the number of items being sold and p is the unit price (in dollars). Find the marginal revenue function and use it to approximate the revenue realized from the sale of the 81st item. Hint: remember that the revenue function is given by R (x) = pa %3D Type your answer (just the number) in the space below. The revenue realized from the sale of the 81st item is approximately dollars.
