Answer:
0.4
Explanation:
Given that,
Convenience store advertises 50% off frozen slushies: This means that the price of slushies decreases by 50%.
20% Fewer sales of fountain drinks: This means that the quantity demanded of fountain drink decreases by 20%.
Percentage change in the price of slushies = 50%
Percentage change in the quantity demanded of fountain drink = 20%
Cross price elasticity measures the responsiveness of quantity demanded for one good to any change in the price level of the other good.
Therefore, the cross elasticity between slushies and fountain drinks is as follows:
= Percentage change in the quantity demanded of fountain drink ÷ Percentage change in the price of slushies
= 20 ÷ 50
= 0.4
Therefore, the positive cross price elasticity indicates that these are the substitute goods.
