Before selling the bonds, or any part of the bonds, the governing body shall give notice inviting sealed bids in such manner and for such time as the governing body 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 governing body determines that the bids received are not satisfactory as to price or responsibility of the bidders, the governing body may reject all bids received, if any, and either readvertise or sell the bonds at private sale.
