I have a practice problem from my book that I can't figure out. I don't understand how you combine the ratios given to get to the price and forward P/E ratio. If you could help explain how to set up this problem that would be great. Thanks.

A company has a required return of 16%, a profit margin of 3%, a D/E ratio of 1 and total asset turnover of 2 and just paid a $3.00 Dividend.

If the company has a dividend payout ratio of 20%; calculate the price and forward P/E ratio.
