Final answer:
Producer surplus is the difference between the price at which producers are willing to sell a product and the actual market price.
Step-by-step explanation:
Producer surplus is the difference between the price at which producers are willing to sell a product and the actual market price. It represents the extra benefit that producers receive from selling a good or service.
For example, if a producer is willing to sell a product for $10, but the market price is $8, then the producer surplus would be $2. This surplus is a measure of the producer's profit.
Option 1) The difference between the maximum prices producers are willing to sell a product for and the actual market price is the correct answer.
