The "hole" story is it got back to Mark's diagram, except a similar schematic online. You have to find the base voltage from Vin 12. I used the potential divider and got the same as the answer. Good idea for me is to do the voltages and currents. Funny but this basic classroom stuff is never fully addressed in amateur books. Even ARRL will give just one example. Neither did ARRL give resistance values in the examples.
