§ 10. Same—Sale; price.

The authority may sell such bonds in such manner and for such price as it may determine to be for the best interests of the authority, but no such sale shall be made at a price so low as to require the payment of interest on the money received therefor at more than six percent per annum, computed with relation to the absolute maturity of the bonds in accordance with standard tables of bond values, excluding, however, from such computation, the amount of any premium to be paid on redemption of any bond prior to maturity.
