    A is the current value of the investment after t years,
    P is the initial amount invested or principal, r is the interest rate,
    n is the number of compounding periods per year.
    $3,000 is invested in two accounts, Account I which pays 5% interest compounded quarterly, and Account II which pays 5% interest compounded yearly. Using the above function to model these two investments, which function has a greater percentage rate of change?
