Suppose the revenue R, in thousands of dollars, from producing and selling x hundred LCD TVs is given by R(x) = 5x 3 + 35x 2 + 155x for 0 x 10.07.

• Assume that the cost, in thousands of dollars, to produce x hundred LCD TVs is given by C(x) = 200x + 25 for x 0. Find and simplify an expression for the profit function P(x). (Remember: Profit = Revenue - Cost.)
