- Using the following equation for the demand for a good or service, calculate the price elasticity of demand (using the point form), cross-price elasticity with good x and income elasticity. Q=82P+0.10I+Px Q is quantity demanded, P is the product price. P1 is the price of a related good, and I is income. Assume that P= $10, I = 100, and Px = 20.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_forward(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?arrow_forward
- Prove that price elasticity of demand is not the same as the slope of a demand curve.arrow_forwardWhat does a price elasticity of demand of 0.39 mean?arrow_forwardPlot the price and quantity data given in the demand schedule of exercise 1. Put price on the vertical axis and quantity on the horizontal axis. Indicate the price elasticity value at each quantity demanded. Explain why the elasticity value gets smaller as you move down the demand curve.arrow_forward
- 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_forwardThe 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?arrow_forwardSuppose that your demand schedule for pizza is as follows: a. Use the midpoint method to calculate your price elasticity of demand as the price of pizza increases from 8 to 10 if (i) your income is 20,000 and (ii) your income is 24,000. b. Calculate your income elasticity of demand as your income increases from 20,000 to 24,000 if (i) the price is 12 and (ii) the price is 16.arrow_forward
- Suppose that your demand schedule for DVDs is as follows:Price: 8, 10, 12, 14, 16Demand (income =$10000) : 40, 32, 24, 16, 8Demand (income = $12000): 50, 45, 30, 20, 12a. If your income is $10,000, your price elasticity of demand as the price of DVDs rises from $8 to $10 isarrow_forwardThe cross price elasticity between two goods is +0.9, the initial prices of the two goods are P1 = $2 and P2 = $3, the initial quantities of the goods are Q1 = 10,000 and Q2=8000. Calculate the new amount of Q2 demanded if P1 increases to $2.75 Type your numeric answer and submit 21333 Xarrow_forwardThe demand for good X has been estimated by Q xd = 12 − 3Px + 4Py. Suppose that the price of good X (Px) is $2 per unit and the price of good Y (Py) is $1 per unit. (a) Calculate the own price elasticity. Please show your calculations. (b) Calculate the cross price elasticity of demand. Please show your calculations.arrow_forward
