    Hey. Good afternoon.

    2x + 17 = 89

    2x = 89-17

    2x = 72

    x = 72/2

    x = 36

    Sorry my bad english, i'm Brazilian.

    Hi there! The answer is C.

    To find our answer we need to solve the equality given in your question.

    2x + 17 = 89

    Subtract 17 from both sides

    2x = 72

    Divide both sides by 2

    x = 72 / 2 = 36.

    Therefore there are 36 double-occupied apartments.
