Alanna is an organic lettuce farmer, but she also spends part of her day as a professional organizing consultant. As a consultant, Alanna helps people organize their houses. Due to the popularity of her home-organization services, Farmer Alanna has more clients requesting her services than she has time to help if she maintains her farming business. Farmer Alanna charges $25 an hour for her home-organization services. One spring day, Alanna spends 10 hours in her fields planting $130 worth of seeds on her farm. She expects that the seeds she planted will yield $300 worth of lettuce. Alanna's economic profit from farming equals

Local retailers, like the neighborhood drug store, often go out of business because they lose customers. This story demonstrates that
