Q3 The relations describing demand and supply for a hairdresser's service can be showed as the following equations: QD=540-16P Qs=-300+12P Where Q is the number of customers that need hair services and P is the service fee, in dollars. a. At what average fee would demand equal zero? b. At what average fee would supply equal zero? ( c. What is the equilibrium price and output level? d. Suppose demand increases and leads to a new demand curve: QD=624-10P What are the new equilibrium price and quantity? ( e. Suppose new suppliers enter the market due to the increase in demand so the new supply curve is Q 160+ 12 P (demand curve : QD-624-10P). What are the new equilibrium price and equilibrium quantity??

4. Suppose that at a price of $400 per ticket, 300 tick- ets are demanded to fly from Montreal to Vancouver. Now the price rises to $600, and 280 tickets are de- manded. (a) Assuming the demand for tickets is linear, what is the slope of the demand curve? (b) Find the price elasticities at the quantity-price pairs (300, 400) and (280, 600). (c) What should the airline company do if it wants to increase revenue?
5. The quantity demanded of a certain brand of TV is 3000 per week when the unit price is $485. For each decrease in unit price of $20 below $485, the quantity demanded increases by 250 units. The suppliers will not market any TVs if the unit price is $300 or lower. But at a unit price of $525, they are willing to make available 2500 units in the market. Find (a) the demand function, (b) the supply function, (c) the equilibrium quantity and price.
1. Online the timing and tailoring of prices to specific models of products is the key to successful pricing in online markets. And “Thanks to the ready availability of data in online markets, a pricing manager can easily approximate the elasticity of demands for the different products it sells online.” Assuming a 10 percent decrease in price increases sales by 28 percent, calculate the price elasticity of demand? If the wholesale price of the online product is $50 and sells at a price comparison site that charges $.50 per click and boasts a conversion rate of 5 percent (an average of 20 clicks are needed to generate a sale). What price should you charge for the product? What is the optimal markup on cost? 2. The authors assert that price sensitivity is affected by (1) product life cycles, and (2) numbers of competitors. In fact, “when the number of competing sellers doubles, a firm’s elasticity of demand is expected to double (and you should be able to verify this through…
