A majority of the members of Council shall constitute a quorum for the transaction of business at any meeting of Council, but a number less than a quorum may adjourn the meeting from time to time and compel the attendance of absent members in such manner and under such penalties as Council may prescribe. At any meeting at which a quorum is present, any action may be taken by the affirmative vote of a majority of the members of Council present, except that the passage of ordinances and resolutions shall require a majority of those elected or appointed to Council.
