Please help with the following:

1. Are the costs of debt and equity observable in the capital markets?If not how do you estimate that cost of capital?
2. The expected annual cash flow on a restaurant is $300,000 (assume growth = 0%), and my cost of equity capital for restaurants if 33.3% (restaurants are very risky!).What is the maximum price I am willing to pay for that business?A stock has a current dividend of $2.00, a forecasted growth rate of 10%, a beta = 2, market return = 12.4% and the risk-free rate (30 year US T-Bond YTM) = 4%.The current stock price on the NYSE is $15.What is the value of the stock and is the stock over- or under-valued?
