A local office supply store charges $18 to set up their business card printing machine with the design and $0.15 in materials per business card to print. Select [b]all[/b] equations that could represent an expression for the average cost [math]A(x)[/math] of printing a batch of [math]x[/math] business cards.

[size=150]The school band is in charge of a new set of uniforms made with a new logo. A local business charges $140 to set up the logo with the design and $0.25 in materials per logo printed. The function [math]C(x)=\frac{140+0.25x}{x}[/math] represents the average cost per logo if [math]x[/math] uniforms are printed by this business.[/size][br][br]What is the average cost per uniform to get the logo printed on 25 uniforms?[br]

What is the average cost per uniform to get the logo printed on 100 uniforms?

How many uniforms should be printed to have an average cost of $1 per logo?[br]

What will happen to the price as the number of uniforms printed increases?
