(1) For each 100 words, not more than the sum of $10.00 for each insertion for the first four insertions; and

(2) For each subsequent insertion, not more than the sum of $9.00 per 100 words.

In all cases fractional parts shall be charged for at the same rates.

(b) For the purpose of the computation in subsection (a) of this Code section, a block of numbers or a block of letters and numbers shall be counted as one word.

When an intervening space does occur, this space shall mark the start of a new word.

(c) No judge of the probate court, sheriff, coroner, clerk, marshal, or other officer shall receive or collect from the parties, plaintiff or defendant, other or greater rates than set forth in this Code section.
