Multiple Select
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.
A(x)=x18+0.15x
A(x)=x0.15+18x
A(x)=18+x0.15
A(x)=x18+0.15
