Example 1: A 36-month loan for $4,500 accrues interest at a 15% annual
percentage rate (APR), with the payments made at the end of each month. If
interest begins accruing on this loan on February 15, 2004 (so that the first period
begins on March 1, 2004), calculate the monthly payment, with the odd days
counted on the basis of a 30-day month and compound interest used for the odd
period.
