Tapley Dental Supply Company has the following data:
Net income: $240 Sales: $10,000 Total assets: $6,000
Debt ratio: 75% TIE ratio: 2.0 Current ratio: 1.2
BEP ratio: 13.33%
If Tapley could streamline operations, cut operating costs, and raise net income to $300, without affecting sales or the balance sheet (the additional profits will be paid out as dividends), by how much would its ROE increase?
