How do you do Question 8 in the practice problems from the text (page 84)? 

For part A I used Plowback Ration * ROE = 8% for the dividend growth rate, but for the expected return how do we find DIV1, P0, and P1?

How do we solve parts B & C?

I'd like to verify my answers for parts A and B.  For part A I got that earnings will grow 12% and dividends will grow 8%.  For part B, I got that the stock price will drop by 44.4%. 

For part C, I know that the stock price will drop 44.4% (from part B), but how do you figure out what the actual stock price is?
