Example

Dr. Carol Angle, a young pediatrician, invested $30,000 in Berkshire Hathaway in 1957. If Berkshire Hathaway has grown at 23.28% per annum in the last 44 years what is Dr Angle now worth?

pv = 30000
N =  44
i = 23.28

fv= 30000 * (1.2328 ^ 44)
    =299499971.898

Dr Angle is worth $300 million.
