The bonds shall be sold by the board in such manner and in such quantities as may be determined by it in its discretion but not less than 95 percent of the par value thereof.
Before selling the bonds, or any part thereof, the board shall give notice inviting sealed bids in such manner as the board may prescribe. If satisfactory bids are received, the bonds offered for sale shall be awarded to the highest responsible bidder. If no bids are received, or if the board determines that the bids received are not satisfactory as to price or responsibility of the bidders, the board may reject all bids received, if any, and either again give notice inviting bids or sell the bonds at private sale.
