Multiple Choice

Which of the following expressions can be used to compute the price elasticity of demand?

• A)Price elasticity of demand = \( \frac{Q_{1}-Q_{1}}{\left(Q+Q_{2}\right) / 2} * \frac{P_{1}+P_{2}}{\left(P_{2}-P_{1}\right) / 2} \)
• B)Price elasticity of demand = \( \frac{\left(Q+Q_{2}\right) / 2}{\left(Q_{1}-Q_{2}\right) / 2} * \frac{\left(P_{2}-P_{1}\right) / 2}{\left(P_{2}+P_{1}\right) / 2} \)
• C)Price elasticity of demand = \( \frac{Q_{2}-Q_{1}}{Q_{1}+Q_{2}} * \frac{P_{1}+P_{2}}{P_{2}-P_{1}} \)
• D)Price elasticity of demand = \( \frac{Q_{2}-Q_{1}}{Q_{1}+Q_{2}} * \frac{P_{2}-P_{1}}{P_{1}+P_{2}} \)
