    5,040.00

    Step-by-step explanation:

    First, converting R percent to r a decimal

    r = R/100 = 7%/100 = 0.07 per year.

    Solving our equation:

    A = 8000 (1 + (0.07 * 9)) = 13040

    A = $13,040.00

    The total amount accrued, principal plus interest, from simple interest on a principal of $8,000.00 at a rate of 7% per year for 9 years is $13,040.00.
