Question

Suppose the demand function for good X is given by: where is the quantity demanded of good X, is the price of good X, and is the price of good Y, which is related to good X. Using the midpoint method, if the price of good X is constant at $10 and the price of good Y decreases from $10 to $8, the cross price elasticity of demand is about:_________

Answer 1

Quantity demanded is -0.4

Step-by-step explanation:

Quantity demanded is -0.4 if the prices decline from $8 to $10. The cross price elasticity is the change in quantity demanded for the goods when the price of other goods changes. The price change can be minor and the quantity demanded change can be high.
