A. b. e. demands goods ( any item they buy) makes decisions based on preferences (preference of brand of item) weighs costs and benefits (they see which is a better bargain for what they're getting)
Consumers demand goods and services in the product markets in order to satisfy their needs. Their consumption choices are governed by their preferences and by their budget as, although needs are unlimited, resources are scarce. Therefore, in every operation, a consumer has to assess the benefits that he/she will receive from the purchase in comparison to the expenses beared.
