Find the after$-$tax cost of debt using the approximation formula:

Debt: The firm can sell for $$1000$ a $11-$year, $$1,000-$par$-$value bond paying annual interest at a $11\%$ coupon rate. A flotation cost of $2\%$ of the par value is required.

The firm's tax rate is $29\%$

Answer is $8\mathrm{.}02\%$ I just need help plugging the numbers into the formula correctly.

If there is additional information needed, I will re$-$upload the question with the requested info if I have it$.$ Thank you!
