Final answer:
The statement in question is False because the return on investment (ROI) is calculated differently.
Step-by-step explanation:
The statement in question is False. The return on investment (ROI) is actually calculated by dividing the net profit by the cost of investment, and then multiplying the result by 100 to express it as a percentage.
Operating income is not the same as net profit. Operating income is the amount of income generated from a company's normal business operations, before taking into account interest, taxes, and other non-operational expenses.
