  including the right to approve the proposed amendment as submitted or to
  increase  or  decrease  the amounts of funds proposed to be appropriated

  such borough president and it is concurred in by the mayor.
    b.  Upon the adoption of any such amendment by the  council, it  shall
  be  certified  by the mayor, the public advocate and the city clerk, and
  the capital budget shall be amended accordingly.
    c.  Not later than five days after such certification  such  amendment
