Final answer:
The cross-price elasticity of demand measures the responsiveness of the quantity demanded of one good to a change in the price of another good. For substitute goods like coffee and tea, a higher price for tea would lead to a greater quantity of coffee consumed.
Step-by-step explanation:
The cross-price elasticity of demand measures the responsiveness of the quantity demanded of one good to a change in the price of another good. For substitute goods like coffee and tea, a higher price for tea would lead to a greater quantity of coffee consumed. So, in this case, we would expect a positive cross-price elasticity of demand between coffee and tea.
