In the United States, what are the two things that determine the earnings of workers?

price and availability

location and costs

supply and demand

form and function

C. Supply and demand

Explanation:

Supply and demand is where if the consumers want more of something, the companies will make more of whatever is needed. Wages are in the long run, affected by supply and demand. If there is a very high need for something, than the workers will be working more and will receive a higher paycheck, and vice versa.
