Please show all work so I can learn how to do it!!! Thank you!

You would like to find the cost of capital for a privately-owned chain of grocery stores, Greenwald Groceries. To perform this analysis, you have collected data on publicly-traded chains of grocery stores that are comparable to Greenwald. You estimate that Greenwald's asset beta (unlevered beta) is equal to the weighted-average asset beta for the four comparable firms, as discussed in part (b). The information on comparable firms should be used in your computations as presented in the table below (all figures are in $ bil., except for betas). The tax rate for Greenwald Groceries and its peers is 34%. The annual risk-free rate is 5%, and the expected annual return on the market is 11%. You may assume that the enterprise value for all peers consists only of debt and equity. a) Compute the asset beta (unlevered beta) for each firm in the peer group. b) Find the industry beta based on the weighted average of the unlevered betas in the peer group, where the weight of each firm is equal to the ratio of the firm's enterprise value to the combined enterprise value of the four firms in the peer group. This approach is often used in the industry to assign greater weights to larger firms which account for a greater share of the industry. c) The management of Greenwald would like to evaluate two options for its capital structure: Option 1: 50% equity and 50% debt Option 2: 75% equity and 25% debt Based on the industry beta computed in part (b), find the equity beta (levered beta) for Greenwald under Option 1 and under Option 2. d) Greenwald's debt consists of bonds with semiannual coupon payments. Under option 1, the yield-to-maturity (YTM) on Greenwald's bonds is 6.6% (stated as an APR). Under option 2, the YTM on Greenwald's bonds is 6% (stated as an APR). Compute the weighted average cost of capital for Greenwald under the capital structure in Option 1 and in Option 2. Which of the two options of capital structure would you recommend to Greenwald
