Suppose that the revenue R(n) in dollars from producing n computers is given by R(n) = 0.4n

Question:

Suppose that the revenue R(n) in dollars from producing n computers is given by R(n) = 0.4n - 0.001n2. Find the instantaneous rates of change of revenue when n = 10 and n = 100. (The instantaneous rate of change of revenue with respect to the amount of product produced is called the marginal revenue.)
