The Formula for the Arc Price Elasticity Can Be Written $\Delta$

question 37

Multiple Choice

The formula for the arc price elasticity can be written (where $\Delta$ Q denotes the change in Q) as:

• A) \(\eta\) = [\(\Delta\)Q /(Q₁ + Q₂)]/[\(\Delta\)P/(P₁ + P₂)].
• B) \(\eta\) = [\(\Delta\)Q /(Q₁ + Q₂)]/[\(\Delta\)P/(Q₁ + Q₂)].
• C) \(\eta\) = [\(\Delta\)Q /(P₁ + P₂)]/[\(\Delta\)P/(Q₁ + Q₂)].
• D) \(\eta\) = [\(\Delta\)P /(P₁ + P₂)]/[\(\Delta\)Q/(Q₁ + Q₂)].
• E) none of the above.
