Guest: find the amount of time required to double an amount at 4.44% if the interest is compounded continuously
The formula is
S=A(1+i)
n where S is future value
A is present value
n is the number of compounding time periods
i is the interest rate per time period.
Now there are some problems with your question.
First I suppose i can assume that you meant 4.44% per annum. But I don't think that you really mean that it compounds continuously.
Maybe it compounds daily or weekly or monthly or yearly or some other time period
This needs to be specified before the question can be answered any further.
