In 2005 the monorail in a certain city charged $2 per ride and had an average ridership of about 29,000 per day. In December 2005 the monorail company raised for the fare to $4 per ride, and average ridership in 2006 plunged to around 19,000 per day. Use the given information to find a linear demand equation.

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) =.

When Green Eggs and Ham are sold for $4.00 per apple at Whoville, approximately 2500 servings are sold. When the price is raised to $4.50 per Green Eggs and Ham, the number of servings sold drops to 2250. The cost of producing and shipping the Green Eggs and Ham can be modeled by, C = 3000 + .6x Assuming that the demand function is linear, what price will yield a maximum profit
