Answer:
a) unemployment rate = 15
b) unemployment rate = 2.5
Explanation:
unemployed people are those who are willing and available to work and have actively been seeking a job in the past four weeks. This accurately describes the 12 people who are willing, able and looking for work but cannot find jobs. To calculate the unemployment rate in percentage, the following formula is used:

Where:
a) Number of unemployed = 12
Labour force = 80 (number of people over 16 years of age)

b) if 10 of the unemployed people get discouraged and give up looking for work, the number of unemployed becomes 2 persons, (12 - 10 = 2).

 
        
             
        
        
        
Answer:
differential revenue = $7
so correct option is a.$7
Explanation:
given data 
Product A costs = $6
contribution margin = $3
Product B costs = $12
contribution margin = $4
to find out 
the differential revenue for this decision
solution
we get here the differential revenue for this decision that is express
so first we get here selling price for both product that is 
selling price product A = Product A costs + contribution margin
selling price product A  = $6 + $3 = $9 
and 
selling price product B   = $12 + $4 = $16
so now we get differential revenue that is 
differential revenue = selling price product B - selling price product A
differential revenue = $16 - $9 
differential revenue = $7
so correct option is a.$7
