Question

a local office supply store charges $14 to set up their business card printing machine with the design and $0.05 in materials per business card to print. Write an equation that represents the average cost C of printing x business cards

Answer 1

The equation that represents the average cost C of printing x business cards is: C = 14 + 0.05x

How to write the equation

The fixed cost of $14 for setting up the printing machine with the design. This cost is independent of the number of business cards printed.

The variable cost of $0.05 per business card. This cost increases proportionally with the number of business cards printed.

x: This represents the number of business cards printed.

C: This represents the total cost of printing x business cards.
