Answer:
The correct answer is letter "B": perform an activity at a lower opportunity cost.
Explanation:
Comparative advantage is the ability of an individual, company, or country to produce a good or service at a lower opportunity cost than its competitor. Having a comparative advantage does not mean that one entity is absolutely better than another at producing a good or service. It means that it sacrifices less to do so.
 
        
             
        
        
        
Answer:
The 1-day rate of return on the index = 5.36%
Explanation:
Index Value = Sum of (Outstanding Shares*Share Price)
       q          p           mv              q1            p1          mv1
640,000   16    10240000      640000    20     12800000
540,000   24   12960000      540000    22     11880000
240,000   55   <u>13200000</u>  240000    57     <u>13680000</u>
                         <u>36400000 </u>                                <u>38360000</u>
Note: q/q1 = no of shares, p = price per share, mv/mv1 = market value, p1 = changed price per share
Return = (Index Value Today - Index Value Yesterday)/Index Value Yesterday
Return = (38360000 - 36400000) / 36400000
Return = 0.05385
Return = 5.36%
