When the price is $6.00, the quantity demanded is 20. When the price is $9.00, the quantity demanded is 16. Calculate the price elasticity of demand. You must use the midpoint formula. Given the elasticity of demand, a 10% increase in price will cause quantity demanded to fall by what percentage? Explain your answer. Is this demand elastic or inelastic? Explain your answer. What is assumed about consumer income when you measure the price elasticity of demand? Walmart advertises that it has rolled back prices. If Walmart is rolling back prices to raise revenues, should it roll back prices on products that have a price elasticity of demand that is elastic or inelastic? Explain your answer.

In 2019, 360,000 electric vehicles (EVs) were sold in the United States. Show your formula and calculation steps. a. Suppose the average price of these cars was $40,000. Calculate price elasticity of demand if a $2,000 tax credit caused an increase in sales by 20,000 EVs. b. Calculate cross-price elasticity if a 20 percent increase in the price of gasoline caused an increase in sales of EVs by 30,000.
According to the U.S. Department of Energy, the average price of gasoline in the U.S. fell by 14% in 2015. The number of hybrid electric vehicles (HEV) sold in the U.S. fell by 36% in the same year. Calculate the cross-price elasticity of demand for HEVs and gasoline. Round answer to one place after the decimal.

The accompanying table lists the cross-price elasticities of demand for several goods, where the percent quantity change is measured for the first good of the pair, and the percent price change is measured for the second good. ( please see image) a. Explain the sign of each of the cross-price elasticities. What does it imply about the relationship between the two goods in question? b. Compare the absolute values of the cross-price elasticities and explain their magnitudes. For example, why is the cross-price elasticity of McDonald’s burgers and Burger King burgers less than the cross-price elasticity of butter and margarine? c.

The price elasticity of demand for discs is equal to -0.375 and demand is inelastic. Od. The price elasticity of demand for discs is equal to -1 and demand is unit elastic.
A rise in the price of a muffin from $2 to $3 results in a fall in the quantity demanded of muffins from 200 million to 160 million a day. Moreover, at today's price of a donut of $1.50, the quantity demanded of donuts increases from 70 million to 100 million a day. Calculate the price elasticity of demand for muffins (show calculations) Is the demand for muffins elastic or inelastic? Calculate the cross elasticity of demand for donuts with respect to the price of a muffin. (show calculations) Based on the above calculation how would you characterize the relationship between muffins and donuts? Why would the business owner want to know this? Only typed solution
