Which of the following would be an example of complementary goods?

Complementary goods are items that are typically consumed together, meaning that the demand for one good increases when the price of the other good decreases. In the case of the correct answer regarding hot dogs and hot dog buns, these two items are commonly paired and are often bought at the same time. If you buy hot dogs, you are likely also going to purchase buns, creating a direct relationship between their demand.

This relationship is a hallmark of complementary goods. When hot dogs are on sale, customers are more likely to buy them and, consequently, they will also seek out hot dog buns to accompany them. This interdependence makes hot dogs and buns a perfect example of complementary goods.

While chips and salsa, peanut butter and jelly, and salt and pepper can also be seen as complementary to varying degrees, the strong association and typical purchasing behavior between hot dogs and buns make them the most fitting example in this context.
