    1) If you invest $2,000.00 at a rate of 4% APR for 3 months and the interest is compounded monthly then in 3 months. It will be worth $2,020.07.

    So subtracting $2,000 from $ 2,020.07

    we get.

    $20.07

    2) I = Prt

    I = 4,000 * 0.05

    I = $200

    200 / 10 = 20 hours of work
