Final answer:
Money serves three main purposes: a medium of exchange, a store of value, and a unit of account.
Step-by-step explanation:
The three main purposes of money are:
- A Medium of Exchange: Money is used as a way of buying things and exchanging goods and services. It simplifies transactions by providing a common currency to assign specific values to goods and services.
- A Store of Value: Money acts as a means of saving and storing wealth. It allows individuals to hold onto their purchasing power for future use and prevents the value of the money from depreciating over time.
- A Unit of Account: Money serves as a standard unit of measurement to compare the value of different goods and services. It helps in determining the relative worth or cost of items and facilitates economic calculations.
