What happens to the demand for a complement if the price of one good increases?

When the price of one good increases, the demand for its complement typically decreases. Complements are goods that are consumed together, such as coffee and cream or printers and ink cartridges. When the price of one of these goods rises, consumers are likely to buy less of it. As a result, the demand for the complementary good declines because fewer consumers are consuming the first good, which decreases the overall consumption of both goods.

For instance, if the price of coffee rises, some consumers may choose to buy less coffee, which in turn can lead them to purchase less cream, since they are no longer consuming coffee at the same rate. This relationship between complementary goods highlights the interconnectedness of consumer choices in the marketplace, where the demand for one good is influenced by the price changes of another good.
