If by reason of the operation of RCW
84.52.043 and
84.52.050, as now or hereafter amended the statutory dollar rate limitation applicable to the levy by a taxing district has been increased over the statutory millage limitation applicable to such taxing district's levy in the preceding year, the limitation on the dollar rate amount of a levy provided for in this chapter shall be increased by multiplying the otherwise dollar limitation by a fraction, the numerator of which is the increased dollar limitation and the denominator of which is the dollar limitation for the prior year.
