Rowe and Company has a debt ratio of 0.50, a total assets turnover of 0.25, and a profit margin of 10 percent. The president is unhappy with the current return on equity, and he thinks it could be doubled.  This could be accomplished (1) by increasing the profit margin to 14 percent and (2) by increasing debt utilization.  Total assets turnover will not change.  What new debt ratio, along with the 14 percent profit margin, is required to double the return on equity?
