Answer:
$100
Mona Lisa painting
Explanation:
To start with, I will list the 3 primary functions of money, which are;
store of value,
unit of account, and
medium of exchange.
Going by the above, I would say that 2 of the 4 options presented before us are money, why so?
A $100 bill is definitely money, no much explanation is needed here, because it's used daily as a means of exchange between people
2. Euro is not a form of money in the US. While it is a form of money in many other places, it's not in the US because it doesn't satisfy the "medium of exchange" criteria of function of money. Euro can not be spent in a store or anywhere in the country, without it having been first exchanged into dollars
3. Mona Lisa painting, part of the functions of money is to store value, and I believe very much, a painting is a good store of money in that regard.
4. American Express credit card is not a form of money because unlike money
being used essentially, to pay for goods and services directly, a credit card is more or less, a store of wealth that is lent by the bank
