Whenever the question of issuing county bonds for any purpose is submitted to the registered electors of a county, the determination of the approval or rejection of the bond proposition is made in the following manner:
(1) determine the total number of electors who were qualified to vote in the bond election;
(2) determine the total number of qualified electors who voted in the bond election from the tally sheet or sheets for the election;
(3) calculate the percentage of qualified electors voting in the bond election by dividing the number determined in subsection (2) by the number determined in subsection (1); and
(4) when the calculated percentage in subsection (3) is 40% or more, the bond proposition is considered approved and adopted if a majority of the votes cast were in favor of the proposition, otherwise it is considered rejected; or
(5) when the calculated percentage in subsection (3) is more than 30% but less than 40%, the bond proposition is considered approved and adopted if 60% or more of the votes cast were in favor of the proposition, otherwise it is considered rejected; or
(6) when the calculated percentage in subsection (3) is 30% or less, the bond proposition is considered rejected.
