    r=interest rate as a decimal

    n=number of times interest is calculate/year

    t=time in years

    P=principal amount

    A= amount of money after t years at r interest rate calculated n times per year

    Plug in our values

    Is the intrest rate an anual perctent or a monthly percentage? Also, are you investing 2000.00 each year or for the whole 3 year period?

    I will take it as a simple plug and chug quesiton. I think they are investion 2000.00 total and that it is an anual percent rate. In that case you can just plug in your numbers.




    This gives you A3=2348.48

    If you just used the simplified equation that you gave in your quesiton, it wil not account for the intrest on the profit for each year. I would just do it one year at a time, this doesnt account for the intrest being compounded each month, but its better than the 2330 you get if you use the simplified equation.
