Establishment Industries borrows $710 million at an interest rate of 6.7%. Establishment will pay tax at an effective rate of 35%. What is the present value of interest tax shields if:

a. It expects to maintain this debt level into the far future? (Enter your answer in millions of dollars.)

b. It expects to repay the debt at the end of 6 years? (Enter your answer in millions of dollars rounded to 2 decimal places.)

c. It expects to maintain a constant debt ratio once it borrows the $710 million and r_Assets = 10%? (Do not round intermediate calculations. Enter your answer in millions of dollars rounded to 1 decimal place.)

I reallly only need help with part C. The answer that i keep calculating is 808.7. Using 80.87 as the annual tax shield which is correct.
