2. Calculating the price elasticity of demand: A step-by-stepguide
Suppose that during the past year, the price of a virtual reality headset fell from $4,500 to $4,300. During the same time period, consumer sales
increased from 353,000 to 499,000 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.)
