Final answer:
Rosario is an independent contractor since she provides her catering services on a per-project basis and likely controls how the work is performed which distinguishes her from being an employee or an agent.
Step-by-step explanation:
Rosario is a chef and caterer who hires out on a per-project basis to companies with on-location work sites, as well as to the hosts of banquets and other events. In this capacity, Rosario is best described as an independent contractor. An independent contractor is an individual in business for themselves, providing goods or services to another entity as a non-employee.
This is in contrast to an employee who works regularly for an employer, or an agent who acts on behalf of a principal. Since Rosario works on a per-project basis and likely controls how the work is completed, provides her own tools, and operates under her own business name she falls under the category of an independent contractor. this distinction is important for legal and tax purposes, as it affects responsibilities and benefits.
