    After 5 years she will pay $7,200 in interest.
    After 3 years  she will pay $4,320 in interest.
    Interest saved is 7,200-4,320 = $2880

    A= P(1+rt) 
    where A is the total amount accrued, principal plus interest.
    r is the interest rate
    P is the amount invested or owed.
    and t is the time period.
