    A=p (1+i/m) ^mn

    Interest earned

    I=A-p

    A=980 * (1+0.08:4) ^ (4*5)

    A=1,456.23

    I=1,456.23-980

    I=476.23

    A=7,200 * (1+0.04) ^ (8)

    A=9,853.69

    I=9,853.69-7,200

    I=2,653.69

    A=15,520 * (1+0.06:2) ^ (2*4)

    A=19,660.27

    I=19,660.27-15,520

    I=4,140.27
