Assume we have the following demand curve: Qa = 60 – 4P, were Pis the price of the good and Qdis the quantity demanded of the good. Assume the price increases from $5 to $6. What is the priceelasticity of demand for the good in the range of $5 to $6? Use the ARC elasticity formula tocalculate the elasticity estimate.O -2.15-0.58O -1.26O -1.07

(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?
The price elasticity of demand for personal computers is estimated to be 2.2. If the price of personal computers declines by 20 percent, what will be the expected percentage increase in the quantity of computers sold?
The Stopdecay Company sells an electric toothbrush for $25. Its sales have averaged 8,000 units per month over the past year. Recently, its closest competitor, Decayfigh ter, reduced the price of its electric toothbrush from $35 to $30. As a result, Stopde cays sales declined by 1,500 units per month. What is the arc cross elasticity of demand between Stopdecays toothbrush and Decayfighters toothbrush? What does this indicate about the relationship between the two products? If Stopdecay knows that the arc price elasticity of demand for its toothbrush is 1.5, what price would Stopdecay have to charge to sell the same number of units as it did before the Decayfighter price cut? Assume that Decayfighter holds the price of its toothbrush constant at $30. What is Stopdecays average monthly total revenue from the sale of electric toothbrushes before and after the price change determined in part (b)? Is the result in part (c) necessarily desirable? What other factors would have to be taken into consideration?
Suppose you are in change of sales at a pharmaceutical company, and your firm has a new drug that causes bald men to grow hair. Assume that the company wants to earn as much revenue as possible from this drug. If the elasticity of demand for your companys product at the current price is 1.4, would you advise the company to raise the price, lower the price, or to keep the price the same? What if the elasticity were 0.6? What if it were 1? Explain your answer.
What is the formula for line cross-price elasticity of demand?
What does a price elasticity of demand of 0.39 mean?
(Determinants of Price Elasticity) Would the price elasticity of demand for electricity be more elastic over a shorter or a longer period of time?
Using the midpoint formula for calculating the elasticity of supply, if the price of a good rose from $95 to $105, what would be the elasticity of supply if the quantity supplied changed from a. 38 to 42? b. 78 to 82? c. 54 to 66?
Suppose that your demand schedule for DVDs is as follows: Price Quantity Demanded (income = 10,000) Quantity Demanded (income = 12,000) 8 40 DVDs 50 DVDs 10 32 45 12 24 30 14 16 20 16 8 12 a. Use the midpoint method to calculate your price elasticity of demand as the price of DVDs increases from 8 to 10 if (i) your income is 10,000 and (ii) your income is 12,000. b. Calculate your income elasticity of demand as your income increases from 10,000 to 12,000 if (i) the price is 12 and (ii) the price is 16.
