Dubs & Co. has a debt ratio of 0.50, a total assets turnover of 0.25, and a profit margin of 10%. The CEO is unhappy with the current return on equity, and he thinks it could be doubled. This could be accomplished by increasing the profit margin to 14% and increasing debt utilization. Total assets turnover will not change. What new debt ratio, along with the 14% profit margin, is required to double the return on equity?
