    Answer: A is the correct answer

    Step-by-step explanation:

    Isabella deposited $1,400 in a savings account at her bank. This means that her principal, p is $1400.

    Her account will earn an annual simple interest rate of 6.6% and it will be for 13 years. This means that the interest would be fixed since it is on the same principal each year. The formula for simple interest is expressed as

    I = PRT/100

    Where p is principal

    R is the rate

    T is the time.

    I is the interest after t years

    From the information given,

    P = 1400

    T= 13

    R = 6.6

    I = (1400 × 6.6×13)/100

    I = 1201.2

    Total amount = interest + principal

    The amount of money saved after 13 years = 1201.2 + 1400 = $2601.2

    Answer:

    A. $2,601.20

    Step-by-step explanation:

    This is a simple interest problem.

    The simple interest formula is given by:

    E = P*I*t

    In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

    After t years, the total amount of money is:

    T = E + P.

    In this problem, we have that:

    She deposited $1,400 in savings. This means that P = 1400.

    Annual interest rate of 6.6%, so I = 0.066.

    13 years, so t = 13.

    The interest is:

    E = P*I*t = 1400*0.066*13 = 1201.20

    Her total amount is

    T = E + P = 1400 + 1201.20 = 2601.20.

    The correct answer is:

    A. $2,601.20
