If the price of coffee increases, and as a result, the quantity demanded for tea increases, what does this indicate about the relationship between coffee and tea?

When the price of coffee goes up, and people start buying more tea instead, it shows that coffee and tea are substitute goods. This means that when one becomes more expensive, consumers look for a cheaper alternative, which in this case is tea. For example, if a cup of coffee costs $5 and suddenly rises to $7, many people might decide to buy tea instead, especially if tea is still affordable. This behavior demonstrates how changes in the price of one product can affect the demand for another related product. Understanding this relationship helps businesses and economists predict how consumers will react to price changes in the market.
