Answer:
E) If two firms differ only in their use of debt-i.e., they have identical assets, sales, operating costs, interest rates on their debt, and tax rates-but one firm has a higher debt ratio, the firm that uses more debt will have a lower profit margin on sales.
Step-by-step explanation:
Firms that are highly leveraged, i.e. have a lot of debt, have higher costs due to interests that must be paid, so their profit margins are smaller, and their return on assets is also lower, and their risk is much higher also.
But the benefit is that the return on equity is much higher. A greater amount of debt means lower amount of equity, so any profits made must be divided by a smaller amount of stocks or smaller amount of capital invested.
