The Pear company sells pPhones. The cost to manufacture x pPhones is C(x) = – 22 + 59000x + 19253 dollars (this includes overhead costs and production costs for each pPhone). If the company sells x pPhones for the maximum price they can fetch, the revenue function will be R(x) = 26x + 195000x dollars. How many pPhones should the Pear company produce and sell to maximimze profit? (Remember that profit=revenue-cost.)

If total costs for a commodity are given by  C(x) = 850 + 30x  and total revenues are given by  R(x) = 110x − x2,  find the maximum revenue and maximum profit (in dollars) for the given functions.

Suppose a computer manufacturer has the total cost function C(x) = 80x + 3600 (in dollars) and the total revenue function R(x) (a) What is the equation of the profit function P(x) (in dollars) for this commodity? P(x) = (b) What is the profit (in dollars) on 348 items? P(348) = $ (c) How many items must be sold to avoid losing money? X = items = 380x (in dollars).

Your college newspaper, the collegiate investigator, sells for 90 cents per copy. The cost of producing X copies of an edition is given by C(x)=70+0.10x+0.001x^2 dollars. (b) compute the Revenue and Profit, and also the marginal revenue and profit, if you have purchased and sold 500 copies of the last edition.  Revenue=_____ Profit=____ Marginal Revenue=____ Marginal profit=____
