Indicate which of the functions of money (a medium of exchange, a unit of account, and a store of value) each of the following performs in the U. S. economy.

Medium of Exchange Unit of Account Store of Value

House
Japanese yen
U. S. dollar bill

Explanation:

Money is something which is generally accepted as a medium of exchange, unit of value, store of value & standard of deferred payment.

Plastic Credit Card serves as a Medium of Exchange, as it helps in transactions. It is also a form of standard of deferred payment, as the bank collects spent amount from credit card by the customer later

Japanese Yen acts as a Medium of Exchange, as it helps settle transactions.

US Dollar Bill implies that the settlement is to be done later. So, it is a standard of deferred payment.

House is not money. Its just a real estate asset, bought by money. It acts as a store of value,  as preserve for wealth
