Solving Compound Interest Problems PLEASE READ DESCRIPTION:)

I go over examples involving compound growth and continuous compound growth. Some examples require the use of logarithms to solve for an unknown time period. I apologize that this video has some inconsistent rounding errors. The answer to the first equation without round off error is $40387.39 Here are my other PreCalculus lessons involving Logarithms http://www.profrobbob.com/pre-calculus/exponential-functions-and-logarithms Check out http://www.ProfRobBob.com, there you will find my lessons organized by class/subject and then by topics within each class.
