1. Jason, a high-school student, mows lawns for families in his neighborhood. The going rate is $12 for each lawn-mowing service. Jason would like to charge $20 because he believes he has more experience mowing lawns than the many other teenagers who also offer the same service. If the market for lawn mowing services is perfectly competitive, what would happen if Jason raised his price? Do the participants in the market agree that his experience is relevant if the market is perfectly competitive?
2. Refer to the graph below of a perfectly competitive market. How many units will the firm choose to sell, and at what price?

If at some point in the future the market price fell below $6 (for example where Point A is) what would the firm do?

4. Suppose Jill Johnson operates her pizza restaurant in a building she owns in the center of the city. Similar buildings in the neighborhood rent for $4000 per month. Jill is considering selling her building and renting space in the suburbs for $3000 per month, but she decides not to make the move. She reasons: "I would like to have a restaurant in the suburbs, but I pay no rent for my restaurant now, and I don't want to see my costs rise by $3000 per month." Evaluate Jill's reasoning.
