Answer:
Unit of Account
Store of Value
Medium of Exchange
Step-by-step explanation:
Money can be exchanged for goods and services. Darnell exchanged money ($1299) for a computer. For money to be used as a medium of exchange, it should be generally recognised and accepted.
Money is a unit of account. Darnell compared the value of a vacation with that of a computer using their prices.
Money functions as a store of value. Money can be used to store wealth. Darnell kept his wealth (value) as money in his checking account. For money to be used as a store of value, it should be able to retain its value for a long time.
