Final answer:
In the market for grocery store cashiers, individual job seekers are the suppliers of labor, and the grocery stores are the demanders seeking to hire them.
Step-by-step explanation:
When we consider the market for grocery store cashiers, we are looking at the labor market. In this context, the suppliers are the job seekers or individuals willing to provide their labor as cashiers. Meanwhile, the grocery stores are the demanders as they are the ones seeking to hire cashiers.
In all labor markets, the general principle is that the suppliers of labor are the individuals looking for employment, and the demanders for labor are the firms or employers who need workers to operate their business. This structure contrasts with goods markets where firms are generally suppliers producing products and households are demanders purchasing the products.
