Algebra 2 | Unit 2 | Lesson 20: Rational Equations (Part 1) | Practice Problems

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 all equations that could represent an expression for the average cost A(x) of printing a batch of x business cards.

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 C(x)=\frac{140+0.25x}{x} represents the average cost per logo if x uniforms are printed by this business. What is the average cost per uniform to get the logo printed on 25 uniforms?
