Problem 1

You asked me to deposit $12,000 to you for the next five years. There are available options to deposit once a year or $1,000 monthly or $500 for every two weeks and to be made at the beginning or the end of each period. You prefer to make as much possible from this process. The 12,000 is the value for each year, at an interest rate you choose.

Please explain what you do and why there are differences.
