We can calculate total assets by accounting equation, which is total assets equal to total liabilities plus total equity. Using the basic accounting equation:
Total assets = Total liabilities + shareholders’ equity
= total liabilities + ( total common stock + Retained earnings)
= $51.391 million + ($2.540 million + 18.432 million)
= $72.363 million
Therefore, total assets of the firm would be $72.363 million.
