Explanation:

Supply and demand can be defined as economic forces capable of significantly influencing the prices of a product on the market.

The offer corresponds to the quantity of products offered in a market and that the consumer has available for purchase, and the demand corresponds to the quantity of products that the consumer is willing to consume. Therefore, the supply is determined by the producer and the demand by the consumer.
