(2. 3 1 If total costs are c ( x) = 500+ 440x and total revenues are R (X) = 500x - X2, Find the break- even points. ( Enter your answers as a comma - seperated list!) X = ? 2) IF, in a monopoly market, the demand Function for a product is p= 190 - 0.20 x and the revenue Function is REPX, where x is the number of units sold and p is the price per unit, what price will the maximize revenue? Suppose a company has fixed costs of $ 33, 600 and Variable Cost per unit of LX+ 444 dollars, where X Is the total number of units produced. Suppose further that the Selling price of its product is 1868 - 2 x dollars per, Unit (a) Find the break- even points. LEnter your answers as a comma - seperated list . ) X= -?
