    Answer: 540

    Step-by-step explanation:

    Given : The owner of a stereo store wants to advertise that he has many different sound systems in stock.

    Number of different CD players = 6

    Number of different receivers = 10

    Number of different speakers = 9

    We are assuming that a sound system consists of one of each.

    Then by Fundamental principle of counting, we have

    The number of different sound systems can he advertise = (Number of different CD players) x (Number of different receivers) x (Number of different speakers)

    = 6 x10 x 9 = 540

    Hence, the number of different sound systems can he advertise = 540
