50 Section 3: Basic Financial Functions
Example 1: In Example 1 on page 48, we calculated that the payment amount on
a 29-year, $43,400 mortgage at 14Ľ% annual interest is $523.99. If the seller
requests a balloon payment at the end of 5 years, what would be the amount of
the balloon?
Example 2: If you deposit $50 a month (at the beginning of each month) into a
new account that pays 6Ľ% annual interest compounded monthly, how much
will you have in the account after 2 years?
