Q7 For each of the following sets of supply and demand curves, calculate equilibrium price and quantity. a. QD = 2000 - 2P; QS = 2P b. QD = 500 - P; QS = 50 + P c. QD = 5000 - 10P; QS = -1000 + 5P Q8 Annual demand and supply for the Entronics company is given by: QD = 5,000 + 0.5 M + 0.2 A - 100P, and QS = -5000 + 100P where Q is the quantity per year, P is price, M is income per household, and A is adver- tising expenditure. a. What is the value of the slope parameter for the price of the good? Does it have the correct algebraic sign? Why? b. If A = $10,000 and M = $25,000, what is the demand curve? c. Given the demand curve in part b, what is equilibrium price and quantity? d. If consumer incomes increase to $30,000, what will be the impact on equilibrium price and quantity?

Consider the following demand and supply curves. Demand is Qd = 90 - 0.5P and Supply is Qs = 2P. a) Calculate the equilibrium price and quantity. b) Calculate the revenue, economic surplus and consumer surplus received from this product. c) If a per unit tax of $3.00 is added to the supply curve, calculate the new equilibrium price and quantity, and calculate how consumer surplus, marginal value, and total value are affected in this market? Explain.

8. For a product, the demand curve is p = 100e^(-0.008q) and the supply curve is p = 4∙∙q + 10 for 0 ≤ q ≤ 500, where q is quantity and p is price in dollars per unit. (a) At a price of $50, what quantity are consumers willing to buy and what quantity are producers willing to supply? Will the market push prices up or down? (b) Find the equilibrium price and quantity. Does your answer to part (a) support the observation that market forces tend to push prices closer to the equilibrium price? (c) At the equilibrium price, calculate and interpret the consumer and producer surplus.

Please answer D, E, & F. Demand, Supply, consumer surplus, Market Equilibrium, Price floor. The following relations describe monthly demand and supply conditions in the metropolitan area for recyclable aluminum. QD = 80,000 – 20,000Px (Demand) QS = -20,000 + 20,000Px (Supply) where Q is the quantity measured in pounds of scrap aluminum and P is the price in dollars. Answer the following questions: A. What is the condition for market equilibrium? B. Calculate the market equilibrium price and equilibrium output? C. What is the inverse demand curve P = f(QD)? D. Compute the consumer surplus at the equilibrium price. E. What is the inverse supply curve P = f(QS)? F. Compute the producer surplus at the equilibrium price.
