Calculate the return (A) if the bank compounds quarterly (n = 4). Round your answer to the hundredth's place.
Calculate the return (A) if the bank compounds monthly (n = 12). Round your answer to the hundredth's place.
Calculate the return (A) if the bank compounds daily (n = 365). Round your answer to the hundredth's place.
What observation can you make about the size of the increase in your return as your compounding increases more frequently?
If a bank compounds continuously, then the formula takes a simpler, that is

where e is a constant and equals approximately 2.7183.
Calculate A with continuous compounding. Round your answer to the hundredth's place.

Within the United States alone there are states that flood every year and states in drought causing fires and farmlands are at a loss. So why not build waterways to help prevent flooding and send the rain where it is needed. We could view the same predictable flooding on a global scale and build waterways into draught stricken countries and people can farm and thrive.
