The total/aggregate market demand for rubber erasers can be segmented into two components. The first component is the demand for rubber erasers by art students. This demand is given by Qa 10,000-250P. The second component is the demand for rubber erasers by all other purchasers. This demand is given by Qo=15000-500P. a) Draw the demand curve for art students, the demand curve for other purchasers and the aggregate demand curve b) Derive the algebraic expression for the aggregate demand curve. c) If the equilibrium price is $20, determine the consumer surplus for art students.

(Calculating Price Elasticity of Demand) Suppose that 50 units of a good are demanded at a price of Si per unit. A reduction in price to $0.20 results in an increase in quantity demanded to 70 units. Using the midpoint formula, show that these data yield a price elasticity of 0.25. By what percentage would a 10 percent rise in the price reduce the quantity demanded, assuming price elasticity remains constant along the demand curve?
he market supply curve of rubber erasers is given by QS = 35,000 + 2,000P. The demand for rubber erasers can be segmented into two components. The first component is the demand for rubber erasers by art students. This demand is given by qA = 17,000 - 250P. The second component is the demand for rubber erasers by all others. This demand is given by qO = 25,000 - 2000P. Derive the total market demand curve for rubber erasers. Find the equilibrium market price, quantity, and consumer surplus for the total market demand for rubber erasers. The Equilibrium Price is $______, the equilibrium Quantity is ____ erasers, and the consumer surplus is $_____..
Hariri Shuttles (HS) makes two types of shuttles (for looms), type A and type B. The demand for equations for HS shuttles are 9A [Select] = ¶B where PÅ and pÅ are the prices set by HS for type A and type B shuttles, respectively, and 9₁ and q are the corresponding weekly demands for these goods. HS's weekly production cost is c = 30qA+40qB + 1000. (a) The prices that HS should set to maximize their weekly profit are p [Select] [Select] and PB = 100 - 3PA +2PB and 120+ PA 1.5PB (b) The corresponding weekly demands are (c) HS' maximum weekly profit is * = = [Select] [Select] = and B =
Suppose the demand for bicycles is given byQp = 10,000P- and the supply of bicycles is given by Qs = 0.01P3. (a) Using calculus and the given supply and demand curves, find mathematical expressions for the elasticities of demand and supply as a function of the price. Use these expressions to demonstrate that both curves have constant elasticity along their entire length. (b) Find the equilibrium price and quantity in this market mathematically.
You are the manager of medium-sized company that deals in production of make-ups in Ghana. Suppose one morning you heard on the news that the government has imposed a lump sum tax on every unit of make-up sold in the market. In addition, suppose during the same period, the price of a leading substitute product decreases along with the change the effect of the tax mentioned above, how would you expect the equilibrium price and quantity of make-up to change assuming the effect of the lump sum tax is larger? [Illustrate by using a graph].
Star wars coffee mugs are traded in a competitive world market with a price of R180 per cup. Unlimited quantities are available for import into South Africa at this price. On average 10 000 kg are traded each month. The elasticity of demand has been estimated at -0.81 and elasticity of supply at 3.51. Derive the demand equation for the star wars coffee mug. . . A.

You are the Economic Consultant for Zuku Farms Ghana Limited. Zuku produces cowpea in a community where producers are able to switch back and forth between cowpea and groundnut depending on market conditions. Consequently, you were tasked by the management of Zuku and you estimated the demand function for cowpea as follows: where is the quantity of cowpea demanded in bags per month, is the average price of cowpea in Ghana Cedis, is the average price of groundnut in Ghana Cedis, and Y is the income of consumers. Assuming is initially GH¢31.00 per bag, Y is GH¢1001.50. Also that your estimated supply function for cowpea is as follows: QS = -25 + 3.5PC -1.5Pf – 0.5Pg + 0.25R Where Qs is the quantity supplied of cowpea in bags, Pc and Pg are as defined above, Pf is the price of fertilizer per bag, R is the amount of rainfall (in inches). If Pf = GH¢10, R= 40 inches and Pg= GH¢31.00 Find the resulting supply function for cowpea and determine the equilibrium price and quantity.…
Suppose the demand for a product is given by QD=100-5P, where QD is quantity per year measured in kilogram and P is the price in AUD per kilogram. The supply curve for this product is given by QS=4P-8. Calculate the elasticity of demand and supply at the equilibrium price.
Suppose the income elasticity of demand for ProductZ is -0.8 and the cross price elasticity of demand of Product Z with respect to price of Product M is 2.0. Alex owns a factory producing Product Z. a) State and explain the type of good Product Z is. b) Assuming price of Product Z remains unchanged, state and explain using relevant calculations, specifically how the total quantity demanded of Product Z will be affected when the income of the population decreases by 10%, and the price of Product M increases by 15%.
2) Imagine that you have started a firm and own the patent for a new technology that allows for the 3D printing of food. This is a huge nutritional breakthrough since the printer can provide nutritional food for years. Since you are the first with this technology and have patented it, your firm is the only firm that can produce and sell this type of printer. There are no close substitutes for your printer and your data indicates weekly demand is given by the equation Qa = 9000 - 2P. a) Your production analysis indicates that your firm's cost function is C(Q) = F +Q². Illustrate the market, 2 showing the inverse demand curve, the MR curve and the MC curve. Then, compute and illustrate your firm's profit maximizing price and quantity of the printer. How low must the fixed cost be to ensure that the firm is making positive profits? Make sure to clearly label all relevant curves. Finally, what is the markup on the printer (measure markup in the following way: Price/MC)? b) Redraw the…
QUESTION 14 Sunglasses manufacturer Oakley, Inc. produces high-end and low-end versions of their performance sunglanses. They estimate that the demands for their products are given by: High-end sunglasses: P= 130 - 20H , and Low-end sunglasses: P 80 - QL, where Q is measured in 1000 sunglasses, "H" denotes High-end and "L" denctes Low-end Both types of sunglasses are produced on the same production line in the same facility, so the marginal cost of producing and selling both types of sunglasses is constant at $30. Supposing that (1) the two demands are independent and (H) Oakley can produce and market the sunglasses such that the high- and low-end markets are successfully segmented, what are the profit-maximizing prices Oakley would dharge for each version? O oakley will set price equal to marginal cost for both versions, le, P $30. O By the "midpoint rule", PH- $65 and PL $40. OPH- $80 and PL-$55. OPH- $130 and PL $80.
