Problems 7 and 8 refer to the
Consider each of the following price increase scenarios.
- Price increases from $10 to $20. Demand is _____ and total revenue _____.
- Price increases from $30 to $40. Demand is _____ and total revenue _____.
- Price increases from $50 to $60. Demand is _____ and total revenue _____.
(a)
To fill: the given blanks with suitable answer.
Answer to Problem 7PA
The demand is "inelastic" and total revenue "increases".
Explanation of Solution
Since the negative sign shows the inverse relationship between price and demand,
TR when the price is 10 and the quantity is 350.
TR when the price is 20 and the quantity is 300.
The demand is "inelastic" and total revenue "increases".
(b)
To fill: the given blanks with suitable answer.
Answer to Problem 7PA
The demand is "inelastic" and total revenue "increases".
Explanation of Solution
Since, negative sign shows the inverse relationship between price and demand.
TR when price is 30 and quantity is 250.
TR when price is 40 and quantity is 200.
The demand is "inelastic" and total revenue "increases".
(c)
To fill: the given blanks with suitable answer.
Answer to Problem 7PA
The demand is "elastic" and total revenue "decrease".
Explanation of Solution
Since the negative sign shows the inverse relationship between price and demand. So, it should be ignored.
TR when the price is 50 and the quantity is 150.
TR when the price is 60 and the quantity is 100.
The demand is "elastic" and total revenue "decrease".

- Estimates presented in Exhibit 5 show that Android users have a higher price elasticity of demand for apps in the Google Play Store than do iPhone users in the Apple App Store. Why might Android users tend to be more sensitive to app prices than iPhone users? What categories or types of apps (for example, games/social media) do you think have the highest price elasticities?arrow_forwardSuppose a movie theater raises the price of popcorn 10 percent, but customers do not buy any less popcorn. What does this tell you about the price elasticity of demand? What will happen to total revenue as a result of the price increase?arrow_forwardSuppose you learned that the price elasticity of demand for wheat is 0.7 between the current price for wheat and a price 2 higher per bushel. Do you think that farmers collectively would try to reduce the supply of wheat and drive the price up 2 higher per bushel? Explain your answer. Assuming that they would try to reduce supply, what problems might they have in actually doing so?arrow_forward
- For each of the following, identify where demand is elastic, inelastic, perfectly elastic, perfectly inelastic, or unit elastic: a. Price rises by 10 percent, and quantity demanded falls by 2 percent. b. Price falls by 5 percent, and quantity demanded rises by 4 percent. c. Price falls by 6 percent, and quantity demanded does not change. d. Price rises by 2 percent, and quantity demanded falls by 1 percent.arrow_forwardOn Tuesday, the price and quantity demanded are 7 and 120 units, respectively. Ten days later, the price and quantity demanded are 6 and 150 units, respectively. What is the price elasticity of demand between the 7 and 6 prices?arrow_forwardThe 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?arrow_forward
