Ast 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 $435,000. the debt-to-total-capital ratio was 17%, the interest rate on the debt was 7.5%, and the firm's tax rate was 35%. 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. assume that sales, operating costs, total assets, total invested capital, and the tax rate would not be affected, but the interest rate would rise to 8.0%. by how much would the roe change in response to the change in the capital structure? do not round your intermediate calculations.

Employees at a library check out books to patrons. books have an isbn and a name. the library sometimes has multiple copies of the same book. books have one or more authors. a patron is an individual who has an active (non-expired) library card. for each library card, we store the person's first and last names and their address. for each employee, we store their employee id, current salary, first and last name and their address. we also store the employee id of their current manager. each time we check out a book to a patron we need to store the date of the transaction, the employee who checked out the book to the patron, and the library card of the patron. some employees have library cards. if an employee patron turns in a book late, the fine that they pay is a percentage of their salary. some employees are authors who have library cards—they are allowed to check out as many books as they like.
