When a company has an equity beta, a risk free rate of return, a market return, a pretax cost of debt, a debt equity ratio, and no tax rate, how do you solve for the company's asset beta. Can you show me an example with all the steps included. Break it down like so that I can understand how you came up with each calculation and answer. Please help! The original question is:

Johnson company has an equity beta of 1.5, the risk-free rate of return is 3.0 percent, the market return is 14.7 percent, and the pretax cost of debt is 9.4 percent. The debt-equity ratio is .47. If you apply the common beta assumptions, what is the companys asset beta?
