Using your answers to Questions $13$&$14,$ calculate the capital structure weights: E $/$ D $+$ E and D $/$

$D+E.$ For each of the two companies, what fraction of the firm's financing is equity and what fraction

is debt?

As discussed in class, the cost of debt can be difficult to calculate, especially if a corporation has a lot

of bonds outstanding with different yields to maturity $($YTM$),$ or none at all. To approximate the cost of

debt, calculate the average YTM on debt that has the same bond rating as each corporation.

As of the end of fiscal year $2022,$ please assume the following credit ratings for each company:

Starbucks: Baa$2/$BBB

Shake Shack: Aa$2/$AA$|$
