$21\%$ corporate tax rate.

a$.$ How much of the firm's value is accounted for by the debt$-$generated tax shield?

Note: Enter your answer in million rounded to $2$ decimal places.

c$.$ Now suppose that Congress passes a law that eliminates the deductibility of interest for tax purposes after a grace period of

$5$ years. What will be the new value of the firm, other things equal? Assume an $7\mathrm{.}7\%$ borrowing rate.
