An unlevered firm has a value of $800 million. An otherwise identical but levered firm has $60 million in debt at a 5% interest rate. Its cost of debt is 5% and its unlevered cost of equity is 11%. No growth is expected. Assuming the corporate tax rate is 35%, use the MM model with corporate taxes to determine the value of the levered firm

The answer is $821 million - my calculations are off and I cannot figure out how.
