a) Sales and Customers: In the equation (which is not provided, but the concept applies), if: Y is annual sales: This represents the outcome or effect we're interested in measuring. It's likely influenced by other factors. X is customers: This represents a factor that might influence sales. We might manipulate it to see its effect on sales. Therefore, in this case: Independent variable: Customers (X) - This is the variable we can potentially control or change to see its effect on sales. Dependent variable: Annual Sales (Y) - This is the variable that depends on or is influenced by the independent variable (customers). b) Studying and Test Scores: In the professor's scenario: Independent variable: Studying - This is the factor the professor wants to see if it affects test scores. The professor might control the amount of studying assigned or create different study groups. Dependent variable: Test Scores - This is the outcome the professor wants to measure. It's likely influenced by studying but also by other factors like student abilities.

-Please answer to the following questions: What is the price elasticity of demand? Can you explain it in your own words? What is the price elasticity of supply? Can you explain it in your own words? What is the relationship between price elasticity and position on the demand curve? For example, as you move up the demand curve to higher prices and lower quantities, what happens to the measured elasticity? How would you explain that? B-Assume that the supply of low-skilled workers is fairly elastic, but the employers’ demand for such workers is fairly inelastic. If the policy goal is to expand employment for low-skilled workers, is it better to focus on policy tools to shift the supply of unskilled labor or on tools to shift the demand for unskilled labor? What if the policy goal is to raise wages for this group? Explain your answers with supply and demand diagrams. Make sure to properly cite and reference your academic or peer-reviewed sources (minimum 2).
