Inferior goods are to demand increase during economic downturns as complementary goods are to what?

Inferior goods are products that people tend to buy more of when their income decreases, like instant noodles or used clothing. In contrast, complementary goods are items that are often purchased together, like peanut butter and jelly. During economic downturns, when people have less money, they might still want to buy their favorite complementary goods, but they may buy less of them if they can't afford both. For example, if someone usually buys bread and butter together but faces financial difficulties, they might choose to buy only the bread and skip the butter. So, while demand for inferior goods rises in tough times, the demand for complementary goods may decrease if people can't afford to buy both items together.
