Corporate Liability Taxes!!!

The Talley Corporation had a taxable income of $300,000 from operations after all operating costs but before (1) interest charges of $30,000, (2) dividends received of $12,000, (3) dividends paid of $15,000, and (4) income taxes.

What are the firm's income tax liability and its after-tax income? Round your answers to two decimal places. I am struggling trying to figure out all of the amounts. Could you please advise and show me how you get to the result?
