The mean of a set of numbers is found by adding up all the numbers and dividing by the count of numbers present. For the given set of numbers, which includes 5 values (12, 18, 21, c, 13), the mean is: \[\text{Mean} = \frac{12 + 18 + 21 + c + 13}{5}\] You mentioned that the mean is 17. So, we can set up an equation using this information: \[\frac{12 + 18 + 21 + c + 13}{5} = 17\] Now, let's solve this equation to find the value of \(c\): \[12 + 18 + 21 + c + 13 = 5 \times 17\]

\[64 + c = 85\]

\[c = 85 - 64\]

\[c = 21\] Therefore, the value of \(c\) that would make the mean of the set equal to 17 is \(c = 21\).

-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).
