Principle = $15,500 interest rate = 8.75% time = ? years simple interest = $5425.00 solve for the time in years

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.
