I have this question:

Company XYZ has:

b: 69%

Last dividend paid: $25/share

ROE: 15%

# of Shares: 15,897

Its Book Value will be:

1. 537,63$/share
2. 166.67$/share
3. 241.55$/share
4. None of the answers

I know that answer is the first one, but I didn't understand how it was calculated. Could please explain it step-by-step, telling me why we are doing each step? I've been stuck with this question for days.

Thank you so much in advance!
