each race, with 1% being paid to the Montana board of horse racing, and in
addition may retain:
remainder occurring in each calculation on a dollar basis;
odd cents over any multiple of 10 cents in the amount calculated on a dollar

the event a minus pool should occur and the amount calculated on the dollar
basis be less than 10 cents, the association shall pay the amount of five cents
on each dollar bet.
the event a minus pool occurs, the expenses of such minus pool shall be borne
by the licensee.
