The price elasticity of demand is calculated as the percentage change in quantity demanded divided by the percentage change in price. From the table, the change in quantity demanded is -10 (from 20 to 10), and the change in price is $20 (from $40 to $60). The percentage change in quantity demanded is -10/20 = -0.5 (or -50%), and the percentage change in price is 20/40 = 0.5 (or 50%). The price elasticity of demand is -0.5 / 0.5 = -1. The absolute value of -1 is 1, which is not directly listed, indicating a potential misunderstanding in the calculation or interpretation of the choices provided. However, the correct approach to calculating elasticity was described, and the focus should be on understanding the formula and calculation steps.
