1. Find the levered beta for each proposed capital structure given here. Note that the company already has debt in their capital structure, so the existing company beta is a levered beta. You first need to solve for the unlevered beta using the current b_L and current capital structure.
2. Calculate the cost of equity for each capital structure (current and two proposed)
3. Calculate the cost of capital for each capital structure (current and two proposed)
