Answer:

average of the Sophmores = 117.8

Explanation:

given data

group of college students = 90

average for group = 113

Freshmans  = 40

average score = 107

solution

we get here total of group points for all people is

total of group points =  90 × 113 = 10170

and

here Freshman came from group

Freshman came = 40 × 107 = 4280

so

Sophmores  is =  10170  - 4280  = 5890

so

average of the Sophmores is

average of the Sophmores = \frac{5890}{90-40}  

average of the Sophmores = 117.8

mamaluj [8]

The correct answer to this open question is the following.

Although there are no options attached we can say the following.

Do the economic benefits of free trade outweigh the social costs?

Not really, and it all depends on the perspective.

From the big companies and industrial side, free trade has been a success. Free trade has allowed thousands of companies to export their goods with cero import tariffs, benefiting the income. It has allowed multinational companies to go abroad and establishing branches in different parts of the world, basically in underdeveloped nations.

Once there, they paid very low salaries, much less than what they should have paid in their former countries, That is a reason why they moved to underdeveloped countries. So cheap labor is one reason. And other these multinational companies freely exploit the many raw materials and natural resources of that underdeveloped country.
