The future value S of an investment earning 6% compounded continuously is a function of the principal P and the length of time t that the principal has been invested. It is given by S = f(P, t) = P₂0.06t Find f(3500, 20). (Round your answer to the nearest cent.) $ Interpret your answer. If $3500 was invested initially, this is the amount (in dollars) that would be in the account after 20 years. If $20 was invested initially, this is the amount (in dollars) that you would need to deposit each year so that the account earns $3500 in interest over a period of 6 years. ○ If $20 was invested initially, this is the amount (in dollars) that you would need to deposit each year so that the account reaches $3500 in 6 years. If $3500 was invested initially, this is the amount of interest (in dollars) that the account would earn over a 20-year period.
