You can put this solution on YOUR website!
Use the formula A=P%281%2Br%29%5En, where
A= Amount = Principle + Interest
P= Principle which is $2400
r= rate per period, which is .08/3 since there are 3 periods per year.
n= number of periods, which is 3.

A=2400%2A%281%2B.08%2F3%29%5E3

Using a calculator, you should get
A=+2597.17

Now to find the Interest, subtract the Principle.
I= $2597.17-2400=$197.17
