The authority may sell such bonds in such manner and for such price as it may determine
to be for the best interest 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 a greater rate than the interest allowed by the Revenue Bond Law as now provided
or may hereafter be provided by amendment thereto, 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.
