Final answer:
The scenario that best explains how changes in supply and demand affect changes in labor is when the Doggie Spaw hires two more dog groomers to meet the increase in demand.
Step-by-step explanation:
The scenario that best explains how changes in supply and demand affect changes in labor is: The Doggie Spaw gets 15 new customers each week, so the owner hires two more dog groomers to meet the change in demand. This demonstrates the concept of increased demand leading to an increase in labor.
In the other scenarios:
- Juanita hires her usual four people despite a decrease in demand for wrapping. This does not reflect any change in labor due to supply and demand.
- The Cup Cakery supplies cupcakes to more cafes, but the owner refuses to hire more bakers, showing that changes in supply do not always result in changes in labor.
- Jin's goat farm has a decrease in customers, but he keeps his four employees. This example does not reflect changes in labor due to supply and demand.
