In Problem suppose a company has its total cost for a product given by C(x) = 200x + 10,000 dollars and its total revenue given by R(x) = 250x - 0.01x2 dollars, where x is the number of units produced and sold.
(a) Find the marginal revenue function.
(b) Find R(72) and R'(72) and tell what each represents or predicts.
