(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?
Suppose ManTown demand and supply curves for oil is given by ? = 500−4? ? = −100+6? a) Determine which one is the supply curve and which one is the demand curve and why? b) Calculate the equilibrium price and quantity c) Suppose that ManTown demand changes to ? = 600−4?. Find the new equilibrium price and quantity. e) Compare what happens to equilibrium quantities and prices in questions (b) and (c)? f) From equation (1), if the current price is 110, describe what happens to quantities and prices of demand and supply in this market?

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.
What is a relevant example of how a change in the market (including information, preferences, technology, price of alternative goods, regulations, taxes, etc.) has shifted either the supply or demand of a good. How did this change affect the market equilibrium for that good or service? Explain. Next, find a relatively recent news article (within the past year) to support your finding (the news search feature in Google is helpful with this). If you cannot find an article specific to your example, you may find an article about another similar good or service. Talk about the article and its findings, then include the URL.
Suppose IronTown demand and supply curves for oil is given by ? = 500−4? ? = −100+6? Determine which one is the supply curve and which one is the demand curve and why? Calculate the equilibrium price and quantity. Suppose that IronTown demand changes to ? = 600−4?. Find the new equilibrium price and quantity. Compare what happens to equilibrium quantities and prices in questions (2) and (c)? From equation (1), if the current price is 110, describe what happens to quantities and prices of demand and supply in this market?

Please no written by hand solutions 1. Suppose the current price of a good in a market is $10/unit. At this price, the quantity demanded is 20 units while the quantity supplied is 26 units. (i) Show the above numbers in a well-labeled demand and supply diagram. (ii) Is the market in equilibrium currently? If not, what happens to bring it to an equilibrium? 2. Roughly three years ago around this time, the coronavirus pandemic was declared. During this time, the price of typical masks increased sharply in markets around the world. With the help of a well-labelled market (or demand and supply) diagram, explain briefly why this happened.
