Answer:
The answer is: Complementary goods and services
Explanation:
Complementary goods and services are used with another good or service. For example, sugar is complementary to coffee, fuel is complementary to cars, etc.
Usually when the price or the quantity demanded of a complementary good or service changes, the other complementary good will be affected.
In this question, we are told that restaurants and lodging facilities are complementary to beer. So if the price of beer decreases (increasing the quantity demanded), the demand for restaurants and lodges will increase.
