All grants under the provisions of this chapter shall be on a matching basis with the applying council furnishing fifty percent (50%) of the funds and the state grants in no event exceeding an amount equal to the funds supplied by the council. Upon approval of each application and the making of a grant by the board in accordance therewith, the board shall give notice to the applying regional tourist promotion council of such approval and grant, and shall direct the regional tourist promotion council to proceed with its promotional program as described in its application, and to use therefor funds allocated by the regional tourist promotion council for such purposes. Upon the furnishing of said evidence to the board that the particular regional tourist promotion council has proceeded in accordance with the terms of the application, the grant allocated to such agency shall be paid to the council by the board.
The board may, from time to time, make such investigations and audits, and require each participating council to furnish such evidence or proof, to determine that all funds granted under the provisions of this chapter are being handled and expended for the purposes as approved by the board in awarding the grant.
