A company produces a special new type of TV.  The company has fixed costs of $460,000, and it costs $1500 to produce each TV.  The company projects that if it charges a price of $2300 for the TV, it will be able to sell 700 TVs.  If the company wants to sell 750 TVs, however, it must lower the price to $2000.  Assume a linear demand.  If the

A store sells two brands of camping chairs. The store pays $50 for each brand A chair and $100 for each brand B chair. The research department has estimated that the weekly demand equations for these two competitive products to be the following, where p is the selling price for brand A, q is the selling price for brand B, and x and y are the average number of chairs sold per week. Complete parts (A) and (B) below. x = 1119-5p+q y = 291 +p-3q Ine demand Tor X WIII de 689 (Type a whole number.) The demand for y will be 181. (Type a whole number.) Demand equation for brand A Demand equation for brand B .... (B) How should the store price each chair to maximize weekly profits? What is the maximum weekly profit? [Hint: C = 50x + 100y, R= px +qy, and P = R-C.] The equation for P is P(p,q) =.

Exercise 2. The demand per week for a book is 120 copies when the price is $8 each and 80 copies when the price is $10 each. a) Find the demand equation for the book, assuming that it is linear. b) Find the quantity demanded when the price is $13 each. c) Find the price if the quantity demanded id 2 books.
