Answer:
a. If revenues are less than expenses, the company has a net loss and retained earnings decreases.
Explanation:
Retained earnings is defined as the portion of income a company retains for internal operations, reinvest into the business, or repay debt.
It is derived by removing dividends paid to shareholders net income of a company.
So of the revenues of a company are less than its expenses a company will have no choice but to use its retained earnings to run internal operations.
This reduces the retained earnings of the company.
