0 Question 1 If the demand and supply curve for computers is: D=100-6P,S=28+3P Where P is the price of computers, what is the quantity of computers bought and sold at equilibrium? o Question 2 The quantity demanded of Good Z depends upon the price of Z (Pz), monthly income (Y), and the price of a related Good W (PW). Demand for Good Z (Qz) is given by equation 1 below: Qz = 150 - 8Pz + 2Y - 15PW Find the demand equation for Good Z in terms of the price for Z (Pz), when Y is $50 and PW = $6.0 Question 3 Beef supplies are sharply reduced because of drought in the beef-raising states, and consumers turn to pork as a substitute for beef. How would you illustrate this change in the beef market in supply-and-demand terms? 0 Question 4 In December, the price of Christmas trees rises and the number of trees sold also rises. Is this a violation of the law of demand? 0 Question 5 A rm charges $800 for its unique word processor. If total revenue is $56,000 in July, how many word processors were sold that month? 0 Question 6 Find the slope of an assumed linear demand curve for theater tickets, when persons purchase 1,000 at $5.00 per ticket and 200 at $15.00 per ticket. o Question 7 Given the following data: WIDGETS P = 80 - Q (Demand) P = 20 + 2Q (Supply) Given the above demand and supply equations for widgets, find the equilibrium price and quantity.Question 8 Given the following data: WIDGETS P = 80 - Q (Demand) P = 20 + 2Q (Supply) Now suppliers must pay a tax of $6 per unit. Find the new equilibrium price-inclusive price and quantity.0 Question 9 Given the following data: WIDGETS P = 80 - Q (Demand) P = 20 + 2Q (Supply) We saw in the last question the equilibrium quantity will now be 18 (instead of 20) and the equilibrium price is now 62 (instead of 20). Which of the following statements is true: (a) Tax revenue will equal $108 (b) Price increases by $4 (c) Quantity decreases by 4 units (d) Consumers pay $70 (e) Producers pay $36 0 Question 10 Which of the following factors will cause the demand curve for labor to shift to the right? (a) the demand for the product by labor declines. (b) the prices of substitute inputs fall. (c) the productivity of labor increases. (d) the wage rate declines. (e) None of the above
