Revenue R from the sale of x units of a product is found by multiplying the price by the number of items sold. (a) Factor the right side of R = 200x - x². R = (b) What is the expression for the price of the item? The consumer expenditure, in dollars, for a commodity is the product of its market price, p, and the number of units demanded, x. Suppose that for a certain commodity, the consumer expenditure is given by 9,000p - 150p². (a) Factor this in order to find an expression for the number of units demanded. (Simplify your answer completely.) x = units (b) Use (a) to find the number of units demanded when the market price is $33. x = units A company's average cost per unit when x units are produced is defined to be Total cost Average cost = Χ Suppose a company's average costs are given by 6000 Average cost = +35+0.2x. X Express the average-cost formula as a single fraction. Average cost = 3
