Final answer:
To calculate margin, we divide net income by sales: 57,800/400,000 = 0.1445. To calculate turnover, we divide sales by average total assets: 400,000/700,000 = 0.5714. To calculate return on investment (ROI), we multiply margin by turnover: 0.1445 * 0.5714 = 0.0826, or 8.26%. To calculate return on equity (ROE), we divide net income by average total stockholders' equity: 57,800/340,000 = 0.1700, or 17%.
