Problem 9.1.29: should be approximately 34.9 %, not 33.7 %; your answer
might differ by a few tenths of a percent, depending on how many days you
used in a year or between dividend dates, or how many decimal places you
used.

Problem 9.2.19: The problem does not explicitly state how many times the
interest is compounded a year, but the student solutions manual tacitly
assumes monthly compounding. Probably the ``24 months'' in the statement
of the problem hints at monthly compounding.

(4800 - 1000) (1 + r / 12) ^ (12 x 2) = 4600.

Get r = 9.59 %, not 13.04 %.
