I'm having trouble with the following homework problem from a finance class.

Bent Co. at the end of the year will have EPS of $5 and if the firm has a cost of capital of 12%:

A) if the firm decides to pay out all earnings as dividends, what would today's firm value be?

B) if the firm decides to pay out 75%, 50%, or 25% of earnings, and the firm's return on investment is 15%, what firm value will the company have?

That's all of the information provided. Any help would be much appreciated.
