Dollar

A dollar is the basic unit of currency used in the United States. It serves as a measure of value for goods, services, and financial transactions. The dollar is represented by the symbol “$” and is subdivided into 100 smaller units called cents. It functions as a medium of exchange, a store of value, and a unit for pricing. The value of a dollar can fluctuate based on economic factors such as inflation, interest rates, and monetary policy. In a broader sense, "dollar" also refers to currency systems in other countries that use the dollar name or similar denominations.
