Karen runs a print shop that makes posters for large companies. It is a very competitive business. The market price is currently $1 per poster. She has fixed costs of $250. Her variable costs are $2,000 for the first thousand posters, $1,600 for the second thousand, and then $1,000 for each additional thousand posters. What is her AFC per poster (not per thousand!) if she prints 1,000 posters?
