Question 1 Consider ten students who think about rent- ing an inner ring (IR) apartment in College Town. Their reservation prices (in no particular order) are 250, 280, 300, 420, 240, 380, 260, 440, 480, and 400, respec- tively. Suppose the supply of IR apartments is fixed at N = 6, and all landlords have reservation prices of zero. a) Plot an ordered list of the students' RPs in a diagram. b) Plot the (inverse) market demand curve, and the (inverse) market supply curve in a diagram. Explain why your plot in a) is identical (except for the labelling of the vertical axis) to your demand plot in b). c) Find the market equilibrium. How many IR apartments are rented out in a competitive equilibrium? To whom? At which price(s)? Explain.

suppose the demand for shoes is given by qd=40-5p and supply is given by qs=10p-20
The demand function for a certain brand of CD is given by p = -0.01x^2 - 0.2x +10 where p is the unit price in dollars and x stands for the quantity that will be made available in the market by the supplier, measured in units of a thousand. Determiine the producer's surplus if the market price is set at the equilibrium price. (round answer to neareset dollar) P = 0.01x^2 + 0.4x +2
Take this hypothetical situation: Suppose that the supply side of the market for for electric energy is comprised of two sellers: Seller 1 and Seller 2. Let P be the price of one unit of electric energy, and Q be the quantity of electric energy. Seller 1 owns a hydropower factory with a constant marginal cost of $3 and can produce a maximum of 10 units of electric energy. In addition, the hydropower plant has a requirement of a minimum of 3 units of electric energy. Seller 2 owns a solar factory to produce electric energy. This factory has a constant marginal cost of $5 and can produce a maximum of 5 units of electric energy. With this given information, please sketch the market supply by aggregating the two individual supplies. Please label the graph clearly for slopes, kinks, intercepts, etc.

only typed answer Q1 Assume that the demand curve D(p) given below is the market demand for widgets: Q=D(p)=1291−14pQ=D(p)=1291-14p, p > 0 Let the market supply of widgets be given by: Q=S(p)=−5+10pQ=S(p)=-5+10p, p > 0 where p is the price and Q is the quantity. The functions D(p) and S(p) give the number of widgets demanded and supplied at a given price. What is the equilibrium price? Please round your answer to the nearest hundredth. What is the equilibrium quantity? Please round your answer to the nearest integer. What is the total revenue at equilibrium? Please round your answer to the nearest integer.
Economics Suppose that the market demand and supply curves for doughnuts (good X) are given by QD = 50 – 40P + 0.03I + 10PY and QS = -150 + 60P – 10W, where P is price of X, I is the average consumer income, PY is the price of cinnamon pretzels (good Y), and W is the wage for workers producing good X. I = $5,000 Py = $5, W = $10 What is the cross-price elasticity of demand at the market equilibrium? What can you say about the relation between doughnuts and cinnamon pretzels?
The following relations describe monthly demand and supply for a computer support service catering to small businesses.Q D = 3,000 - 10PQ S = -1,000 + 10Pwhere Q is the number of businesses that need services and P is the monthly fee, in dollars.a. At what average monthly fee would demand equal zero?b. At what average monthly fee would supply equal zero?c. Plot the supply and demand curves.d. What is the equilibrium price/output level?e. Suppose demand increases and leads to a new demand curve:
A friend of yours is considering two cell phone service providers. Provider A charges $100 per month for the service regardless of the number of phone calls made. Provider B does not have a fixed service fee but instead charges $0.5 per minute for calls. Your friend's monthly demand for minutes of calling is given by the equation QD=160−80PQD=160−80P, where PP is the price of a minute. With Provider A, the cost of an extra minute is . With Provider B, the cost of an extra minute is . Given your friend's demand for minutes and the cost of an extra minute with each provider, if your friend used Provider A, he would talk for minutes, and if he used Provider B, he would talk for minutes. This means your friend would pay for service with Provider A and for service with Provider B. Use the following graph to draw your friend's demand curve for minutes. Then use the green triangle to help you answer the questions that follow
Assume quantities need not be integers. Demand in a competitive market is Qd(P)=120 – (4/10)*P. If 20 units are transacted, what is the lowest marginal benefit (i.e., MWTP) at which an item is purchased? Round to two decimal places and do not enter a currency symbol. If your answer is $1.125, enter 1.13.
The demand functions for each of two goods depend on the prices of the goods, p1 and p2:qD1=15-3p1+p2, qD2=6-2p2+p1The supply curves, on the other hand, depend on only the own prices:qS1=2+p1, qS2=1+p2 Solve for the equilibrium in this market finding p*1, p*2, q*1, and p*2
Case study 1Oil pump price war Based on an article from The Telegraph, 10 July 2009 “Asda, the supermarket chain, sparked a potential petrol price war yesterday as it cut its fuel prices to 99.9p per litre, declaring there was “little justification” to charge more than £1 at the pumps.The reduction was made on petrol and diesel, representing an average cut of 2p and 1p respectively, at all the company’s 176 forecourts.The move was quickly followed by a pledge from Morrisons that it too would sell petrol for under £1 a litre, signalling the start of a price war. BP said it would cut prices by around 2p at many of its sites, and would continue to respond to local competition.A spokesman for the AA said: “Asda’s price drop marks the start of a new price war. Others will have no choice but to follow.”Asda’s Commercial director David Miles said: “There is no justification for any major retailer selling fuel above £1 per litre – that is why we are delighted to be able to reduce both petrol…
For part 1b, my Professor said the answer is $56 but I'm finding it to difficult to get 56. Can you help? Thanks a lot! Jack is the owner of the only local bar in a small town.He sells whiskey in one-ounce glasses. For simplicity, let’s assume it doesn’t cost Jack anything to run his business. There are two customers, Adam and Burt who are twin brothers. Adam’s demand function is yA = 16 – 2p, and Burt’s demand function is yB = 8 – p (price is measured in dollars and quantity is measured by ounces). Jack knows their demand functions, but the problem is that he cannot tell them apart since they look exactly the same to him. To increase his profits, Jack offers the following two options that his customers can choose from: (1) You can pay $T1 up front and drink as much as you want; or (2) Pay $T2 up front and the price per ounce of whiskey will be $p. 1.a If p = 4, what is the maximal T2 that Jack can charge so that Burt is willing to come to the bar? 1.b What is the maximal T1 that…
