Nick can invest $10,000 in either one of two annuities, annuity a
has a 6% annual interest rate
and requires a starting principal
of $9,000, plus annual $100
deposits for the next 10 years.
annuity b has a 12% annual
interest rate and requires a
starting principal of $9,000,
plus annual $200 deposits for
the next 5 years.
what is the difference between
the final balances of the two
annuities?
