Pregunta 9

To solve this, we recall economic terms: Substitutes are goods that replace each other. Normal goods are those whose demand increases with income. Complements are goods used together (e.g., printer and ink). Secondary goods are not a standard term for this concept. So the correct term for goods used together is complements.

We analyze the economic terms: Surplus is an excess of supply. Price floor is a legal minimum price (e.g., minimum wage). Shortage is excess demand. Price ceiling is a legal maximum price. So the legal minimum price a business can charge is a price floor.

Answer:

c. complements
