In the scenario described, cattle primarily provide the following two functions of money:
-
Unit of account - Cattle serve as a measure to value goods and services. Prices are expressed in terms of cattle, which allows for a consistent way to compare the value of different items.
-
Medium of exchange - Cattle are used as a medium to facilitate transactions for goods and services, allowing people to trade with one another using cattle instead of bartering directly.
Therefore, the correct answers are unit of account and medium of exchange.
