sum into a savings account that pays 7% compounded annual interest and leave the money in the
account for exactly 7 years, at which time you will withdraw the entire amount, since its value at that
moment will be exactly $7,777.77
The bank is even willing to accommodate you by compounding the interest 7 times a year, instead of its
usual monthly compounding (12 times per year).
How much money do you deposit today, so that you have $7,777.77 seven years later?
