    A = $4000

    Explanation:

    given dа ta:

    total investment $12000

    interest on CD = 4%

    Interest on bond = 7%

    the portion invested in the CD is A

    total portion invested as a bond = $12,000 - A

    total portion earned on the CD = 0.04A.

    The total interest gain on the bond = 0.07 (12000 - A).

    equation for the total interest earned is:

    0.04A + 0.07 (12000 - A) = 720

    0.04A + 840 - 0.07A = 720

    -0.03A = - 120

    A = $4000
