Money as a unit of account

So, is that all we need money for? Actually, there's more to it. We also use money as a unit of account, meaning that we use it to compare the values of goods or services to those of other goods or services, and to record those values.

For example, when we check out and compare vehicles, we always try to find the most value for our money. We compare these vehicles by using their values, and we decide which one is better suited for us.
