Complete the table assuming continuously compounded interest.
(Round your answers to two decimal places.)
Initial Investment: $958.54
Annual Rate (%): UNKNOWN
Time to Double: 11 yr
Amount After 10 Years: $1800
:
The continuous interest formula: ,
find the rate for any amt to double in 11 yrs
r =
r = .063 or 6.3% interest
:
Amt after 10 yrs = 1800 at 6.3%, find P
Using a calc find e^.63
1.8776p = 1800
p =
p = $958.67, close to the original amt

The given numbers for the initial investment and the amount after 10 years are irrelevant. The interest rate is exactly determined knowing that the doubling time is 11 years.
to 3 decimal places.
The given initial amount and the amount after 10 years are consistent with that interest rate; but neither of those numbers is needed to determine the interest rate, which is what the question asked for.
