Answer:
Cross-price elasticity of demand = 0.1
Explanation:
We have the formula to calculate the cross-price elasticity of demand as below:
Cross-price elasticity of demand = % change in quantity demanded for product X/ % change in price of product Y
Starbucks raises its price by 5 percent, so that percentage changes in price of Starbucks' products are 5
McDonald's experiences a 0.5 percent increase in demand for its coffee, so that percentage changes in quantity demanded for McDonald's coffee is 0.5
=> Cross-price elasticity of demand = % changes in quantity demanded for McDonald's coffee/ %changes in price of Starbucks' products
= 0.5/5= 0.1
