Answer:
And if we convert this into % we got
See explanation below.
Explanation:
We assume that we have compounding interest.
For this case we can use the future value formula given by:
Where:
FV represent the future value desired = 1000000
PV= represent the present value = 50000
i = the interest rate that we desire to find in fraction
n = number of times that the interest rate is compounding in 1 year, since the rate is annual then n=1
t = represent the number of years= 50 years
So then we have everything in order to replace and we got:
Now we can solve for the interest rate i like this:
And if we convert this into % we got
