question 2

Multiple Choice

The formula for the cross-price elasticity of demand can be written as:

• A) \(\eta\)_XY = (\(\Delta\)Q_X / \(\Delta\)P_Y)(P_Y / Q_X)
• B) \(\eta\)_XY = (\(\Delta\)P_Y / \(\Delta\)Q_X)(P_Y / Q_X).
• C) \(\eta\)_XY = (\(\Delta\)P_Y / \(\Delta\)Q_X)(P_Y / Q_X)
• D) \(\eta\)_XY = (\(\Delta\)P_Y / \(\Delta\)Q_X)(Q_X / P_Y).
• E) none of the above.
