Answer:
$252,900
Explanation:
Stockholders' equity refers to the net assets of a business. In other words, the value of the assets after deducting all liabilities. It is calculated by subtracting total liabilities from total assets.
For Casello,
Total assets = current assets plus fixed assets . Â
 i.e., 437,200+$552,800= $990,000
Total liabilities = current liabilities plus  long-term debt
i.e., Â $318,500 + Â $418,600= $737,100
Stockholder equity = $990,000 - $737,100
=$252,900
