We must find time by using the simple interest formula:
I = P x i x t
I is the interest
P is the total principal
i is the rate of interest per year
t is the total time in years
In this example, when we plug our known values in, our formula looks like this:
t =

t =

t = 4
So time (in years) would be 4 years.
The answer you will be dividing by is 4. hope this helps
