Starting on September 1, 2000 - the day he starts college - and
ending on September 1, 2004, Craig borrowed $6500 a year to pay for
college expenses (i.e. that's 5 withdrawals total).
After graduation, he decided to go to graduate school in
mathematics, and his loans were deferred (i.e. they accrued
interest, but no payments were due). After finishing graduate
school, he began repaying his loans. Beginning on July 1, 2007, he
made monthly payments for 8 years. Each payment increased by 2.6%
over the previous payment. If his loans had a fixed nominal rate of
6% convertible monthly for the entire life of the loans, what was
the size of his first payment?
