9- Last year Hamdi Corp. had sales of $500,000, operating costs of $450,000, and year-end assets (which is equal to its total invested capital) of $370,000. The debt-to-total-capital ratio was 17%, the interest rate on the debt was 7.5%, and the firm's tax rate was 25%. The new CFO wants to see how the ROE would have been affected if the firm had used a 50% debt-to-total-capital ratio.
