To determine the additional fee per brochure, we need to find the difference in cost for each increase in the number of brochures. Looking at the table, we can see that the difference in cost between 40 brochures and 43 brochures is $7.50 (from $600.00 to $607.50), and the difference in cost between 43 brochures and 45 brochures is $5.00 (from $607.50 to $612.50). Therefore, the additional fee per brochure is $7.50.
To determine the printing fee, we need to find the cost when no brochures are printed. Looking at the table, we can see that the cost when no brochures are printed is $600.00. Therefore, the printing fee is $600.00.
Based on these calculations, statement D is not true, as the printing fee is not $250.00.
Therefore, the correct statement is A: The additional fee per brochure is $7.50.
