MakeItBig, Inc. has a total assets turnover of 0.32, a profit margin of 9.64 percent, and a debt ratio of 0.70. The CFO, Ms Ambition, wants to double the current return on equity by making some changes. If she thinks that the profit margin can be boosted to 10 percent, and that she can generate an additional $1.00 of sales revenue generated by every dollar of assets, by how much should she decrease the debt ratio in order to double the return on equity?
