Karen runs a print shop that makes posters for large companies. It is a very competitive business. The market price is currently Si per poster. She has fixed costs of $100. 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.
a. What is her AFC per poster (not per thousand!) if she prints 1,000 posters? What if she prints 2,000 posters? What if she prints 10,000 posters?
b. What is her ATC per poster if she prints 1.000? What if she prints 2,000? What if she prints 10,000?
c. If the market price fell to 95 cents per poster, would there be any output level at which Karen would not shut down production immediately?
