The profit P(x) of selling x items is P(x) = xp(x) - C(x) (revenue minus costs). The average profit per item when x items are sold is P(x) / x and the marginal profit is dP / dx. The marginal profit approximates the profit obtained by selling one more item given that x items have already been sold. Consider the following cost functions C and price functions p. Complete parts (a) through (d) below. C(x) = - 0.03x2 + 50x + 120, p(x) = 200, a = 500 a. Find the profit function P.
