Pulsar also manufactures a series of 20-in. flat-tube digital televisions. The quantity x of these sets demanded each week is related to the wholesale unit price p by the following eau P = -0.055x + 230 The weekly total cost incurred by Pulsar for producing x sets is represented by the following equation. C(x) = 0.000004x3 - 0.1x2 + 590x + 87000 (a) Find the revenue function R. R (X ) = Find the profit function P. P(X ) = (b) Find the marginal cost function C . C'( X ) = Find the marginal revenue function R '. R '( X ) = Find the marginal profit function P '. P ' ( x ) = (c) Compute the following values. (Round your answers to two decimal places.) C '(2700) = R '(2700) = P '(2700) =
