Final answer:
If a business is expanding and needs more workers, the pay for workers may increase due to high demand for labor and the competition to attract necessary talent.
Step-by-step explanation:
When a business is expanding and in need of more workers, the worker's pay may increase. This is because competition in the workforce helps determine how much people will be paid. If the demand for labor is high due to business expansion and there are not enough workers available, businesses may offer higher wages to attract the necessary talent. Conversely, when many people are unemployed and jobs are scarce, workers may be willing to accept lower wages, allowing businesses to maintain or increase profits by not raising wages. Therefore, in the scenario where a business is expanding and seeking more employees, the answer is A. Increase.
