Which of these goods are complements?

Question

coffee and tea

contact lenses and glasses

canoe and paddles

milk and cream

Answer 1

Complements are goods that are often used together, such that the demand for one increases the demand for the other.

Among the options you provided, the following are complements:

• Milk and cream: These are often used together in various recipes and beverages.
• Canoe and paddles: A canoe typically requires paddles for use, making them complementary goods.

The other options, coffee and tea, and contact lenses and glasses, are more substitutes than complements, as people typically choose one over the other, depending on their preferences.
