If the cross price elasticity of demand between two goods A and B is positive, what does this indicate about the relationship between these goods?

When the cross price elasticity of demand between two goods A and B is positive, it means that the two goods are substitutes. This means that if the price of good A goes up, people will buy more of good B instead, because they see B as a similar option. For example, if the price of coffee increases, some people might choose to drink tea instead, since both are beverages that can serve a similar purpose. This positive relationship shows how the demand for one good can be affected by the price change of another good. Essentially, when one becomes more expensive, the other becomes more attractive to consumers.
