We can solve this problem using algebraic equations. Let's denote the height of Lili as L.

We know that the average height of Aranka, Böske, Cili, Delinke, and Lili is 172 cm. This means that the sum of their heights is 5 * 172 = 860 cm.

We are also given that Aranka and Cili are both 172 cm tall. This means that their combined height is 2 * 172 = 344 cm.

We are told that the sum of Böske's and Delinke's heights is 336 cm.

Let's set up the equation:

B + D = 336

We need to express Böske's and Delinke's heights in terms of Lili's height. Since we know that Aranka and Cili are both 172 cm tall, the sum of their heights is 2 * 172 = 344 cm. So, the combined height of Böske, Delinke, and Lili is 860 - 344 = 516 cm.

We can write another equation based on this information:

B + D + L = 516

Now we can substitute the value of B + D from the first equation into the second equation:

336 + L = 516

Finally, we can solve for Lili's height:

L = 516 - 336 = 180 cm

Answer: Lili is 180 cm tall.

25) Paulo saves R$250.00 per month and keeps the money in a safe in his own home. At the end of 12 months, deposit the total saved into the savings account. Consider that, each year, deposits are always carried out on the same day and month; the annual yield on the savings account is 7%; and, the yield total is obtained by the interest compounding process. So, the amount that Paulo will have in his savings account after 3 years, from the moment you started saving part of your money monthly, it will be A) R$6,644.70. B) R$ 9,210.00. C) R$ 9,644.70.

-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).
