The board shall then certify the amount so determined and apportioned to the board of trustees of the college and to each participating board of chosen freeholders.
The board of chosen freeholders, upon receipt of such certificate, shall appropriate the amount certified therein and shall raise such amount in the manner provided for by N.J.S. 18A:64A-18 and 18A:64A-19.
