2. Calculating the price elasticity of demand: A step-by-stepguide Suppose that during the past year, the price of a laptop computer fell from $2,100 to $1,820. During the same time period, consumer sales increased from 429,000 to 530,000 laptops.   Calculate the elasticity of demand between these two price–quantity combinations by using the following steps. After each step, complete the relevant part of the table with the appropriate answers. (Note: For decreases in price or quantity, enter values in the Change column with a minus sign.)   Original New Average Change Percentage Change Quantity             474.75% / 10.53% / 21.06% Price             -700% / -14.29% / -7.14%   Step 1: Fill in the appropriate values for original quantity, new quantity, original price, and new price. Step 2: Calculate the average quantity by adding the original quantity and the new quantity, and then dividing by two. Do the same for the average price. Step 3: Calculate the change in quantity by subtracting the original quantity from the new quantity. Do the same for the change in price. Step 4: Calculate the percentage change in quantity demanded by dividing the change in quantity by the average quantity. Do the same to calculate the percentage change in price. Step 5: Calculate the price elasticity of demand by dividing the percentage change in quantity demanded by the percentage change in price, ignoring the negative sign. Using the midpoint method, the elasticity of demand for laptops is about (0.68 / 0.74 / 1.47 / 2.95).

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.

Calculating the price elasticity of demand: A step-by-stepguide Suppose that during the past year, the price of a virtual reality headset rose from $4,100 to $4,550. During the same time period, consumer sales decreased from 420,000 to 313,000 headsets. Calculate the elasticity of demand between these two price–quantity combinations by using the following steps. After each step, complete the relevant part of the table with the appropriate answers. (Note: For decreases in price or quantity, enter values in the Change column with a minus sign.)   Original New Average Change Percentage Change Quantity              Price                Step 1: Fill in the appropriate values for original quantity, new quantity, original price, and new price. Step 2: Calculate the average quantity by adding the original quantity and the new quantity, and then dividing by two. Do the same for the average price. Step 3: Calculate the change in quantity…

Suppose that during the past year, the price of a laptop computer fell from $2,950 to $2,450. During the same time period, consumer sales increased from 430,000 to 619,000 laptops.   Calculate the price elasticity of demand between these two price–quantity combinations by using the following steps. After each step, complete the relevant part of the table with the appropriate answers. (Note: For decreases in price or quantity, enter values in the Change column with a minus sign.)     Original New Average Change Percentage Change Quantity              Price                Step 1: Fill in the appropriate values for original quantity, new quantity, original price, and new price.   Step 2: Calculate the average quantity by adding the original quantity and the new quantity and then dividing by 2. Do the same for the average price.   Step 3: Calculate the change in quantity by subtracting the original quantity from the new quantity. Do…
