Here are book$-$ and market$-$value balance sheets of the United Frypan Company $($figures in $ millions$)$:

Assume that MM$\text{'}$s theory holds except for taxes. There is no growth, and the $$70$ of debt is expected to be permanent. Assume a $21\%$

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.

b$.$ What is United Frypan's after$-$tax WACC if $r_{\text{D}\text{e}\text{b}\text{t}}=6\mathrm{.}3\%$ and $r_{\text{E}\text{q}\text{u}\text{i}\text{t}\text{y}}=16\mathrm{.}7\%?$

Note: Do not round intermediate calculations. Enter your answer as a percent 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 $6\mathrm{.}3\%$ borrowing rate.

Note: Do not round intermediate calculations. Enter your answer in million rounded to $2$ decimal places.
