Please, Any help on tis problem will be greatly appreciated

Pitt Beverage (PB) Capital Cost Finance-Moeller PB is a publicly listed brewery and bottling company. The firm uses standard weighted average cost of capital (WACC) and CAPM calculations to find its cost of capital. The firm has two divisions. The brewery division's market value (V) is twice the size of the bottling division's market value. The target-level of (long-term) debt to market value is one-third (1/3) for PB (25% for the brewery division and 50% for the bottling division respectively). Because of the firm's relatively high level of debt, it is not reasonable to assume the beta of debt is zero but you can assume that small changes in capital structure do not affect the beta of debt. Projects undertaken by the brewery division are usually short-term (up to 1 year) projects. Bottling projects usually involve longer-term investments, averaging approximately 10 years. Use the financial information on the next page to answer the following questions (do them in order!): a. Calculate the cost of capital (RWACC) for PB. b. Calculate the cost of capital (RWACC) for the brewery division of PB. c. Calculate the cost of equity for the bottling division of PB. d. The CFO has just returned from a meeting with PB's bankers and is seriously considering switching a large portion of debt from fixed to floating rate and altering the target capital structure to keep a constant dollar amount of debt rather than a constant proportion. How would that change your calculations above? You do not have to re-do them, just give a brief description of the difference.
