Final answer:
If sales and operating income remain the same, return on investment will decrease if turnover increases.
Step-by-step explanation:
If sales and operating income remain the same, return on investment will decrease if turnover increases. Return on investment is a financial metric that measures the profitability of a company's investment. It is calculated by dividing the company's operating income by its total assets. When turnover increases, it means that the company's assets are being used more efficiently, resulting in a higher return on investment.
