If the price of a substitute good increases, what is likely to happen to the demand for the original good?

When the price of a substitute good increases, the demand for the original good is likely to increase as well. A substitute good is something that people can use instead of another product; for example, if the price of butter goes up, people might buy more margarine instead. This happens because consumers want to save money, so they look for alternatives that are cheaper. As more people buy the original good, its demand rises, which can also lead to an increase in its price. In this way, the relationship between substitute goods helps to explain how market demand works.
