　　The American economic system is organized around a basically private enterprise. It’s (36) market-oriented ecomomy in which consumers determine what shall be producted by spending their money for those goods and services. Private businessmen, (37) striving to make their profits, produce these goods and services in (38) competition with other businessmen, and the profit (39) motive, operating under competitive pressures, largely (40) determines how these goods and services are produced. Thus, in the American economic system it is the demand of individual consumers, (41) coupled with desire of businessmen to gain more profits and the desire of individuals to (42) maximize their incomes, that together determine what shall be produced and how (43) resources are used to produce it.

If the product is in short reply relative to the demand, the price will be a bit up and some consumers will be eliminated from the market. If, on the other hand, (45) more supply of products results in reducing its cost, this will tend to increase the supply offered by seller-producers which in turn will lower the price and permit more consumers to buy the product . Thus, price is the regulating mechanism in the American economic system.
