Question

When interest is compounded continuously, the balance in an account after t years is given by

P(t) = P0ekt, where P0 is the initial investment and k is the interest rate. Suppose that P0 is

invested in a savings account where interest is compounded continuously at 9% per year.

Express P(t) in terms of P0 and 0.09

Answer 1

P(t) = P0ekt should be P(t)=P₀e^kt which for k=9% is just P₀e^.09t

Answer 2

P(t)=P0e^.09*t
