If Kerry writes a check for a new car, she is using money as a-

Medium of Exchange, brainliest please?

Explanation:

Money can be used in different ways such as being a medium of exchange, a store of value and unit of account. The relevant use here is as a Medium of exchange.

At some point in history, humans used the barter system to trade which means that they exchanged goods for other goods. This was a inefficient because it could be quite bothersome deciding how much of one good to exchange for another.

Money changed all that because it was able to value goods relatively and therefore be used as a medium of exchange for goods. In writing a cheque to purchase a car, Kerry is using exchanging money for the car making it a medium of exchange.

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
