Money working as a medium of exchange replaces which older arrangement?

Question

Accepted Answer

A. Barter, where goods and services trade for other goods

1. As a medium of exchange, money makes transactions easier.
2. Having a common form of payment is much less complicated than a barter system, in which goods and services are exchanged for other goods and services.
3. Money therefore lets the exchange of products be a simple process instead of a search for a matching swap.
4. Credit and lending both still need money to state the amount owed, so neither is the arrangement money replaced.
