Final answer:
To calculate average total liabilities, add up all the liabilities and divide the sum by the number of periods. The average liability when deposit is 300 and equity is 30 for a period of one is 330.
Step-by-step explanation:
To calculate average total liabilities, you need to add up all the liabilities for a given period and then divide the sum by the number of periods. In this case, the liabilities are deposits and equity.
Step 1: Add the deposits and equity together: 300 + 30 = 330.
Step 2: Divide the sum by the number of periods, in this case, 1: 330 ÷ 1 = 330.
So, the average total liabilities is 330.
