The demand for a new computer game can be modeled by p(x) =45.5 7 In x, for 05x5 800, where p(x) is the price consumers will pay, in dollars, and x is the number of games sold, in thousands. Recall that total revenue is given by R(x) = x - p(x). Complete parts (a) through (c) below. E> all Find R(x). R(x) = x(45.5 - 7 In x) b) Find the marginal revenue, R'(x). R'ix) = D
