Answer:
b. $2,000
Explanation:
The computation of the interest amount is shown below:
= Sale value of goods × rate of interest × (number of months ÷ total number of months in a year)
= $40,000 × 10% × (6 months ÷ 12 months)
= $2,000
The 6 months is calculated from June 30 to December 31. 
So, the b option is correct and rest options are wrong.
 
        
             
        
        
        
Answer:
 -3.28
Explanation:
Given that,
Initial quantity, Q1 = 2
Final quantity, Q2 = 0
Change in quantity = Q2 - Q1
                                 = 0 - 2
                                 = -2
Initial income, M1 = $8
Final income, M2 = $15
Change in Income = M2 - M1
                                = $15 - $8
                                = $7
Average quantity:
= (2 + 0) ÷ 2
= 1
Average income:
= (15 + 8) ÷ 2
= 11.5
Therefore,
Percentage change in quantity demanded:
= (Change in quantity demanded ÷ Average quantity) × 100
= (-2 ÷ 1) × 100
= -200%
Percentage change in income:
= (Change in income ÷ Average income) × 100
= (7 ÷ 11.5) × 100
= 60.87%
Income elasticity of demand:
= Percentage change in quantity demanded ÷ Percentage change in income
= -200 ÷ 60.87
= -3.28

Most trade is due to the comparative advantage of an organization's ability to produce a good or service with lower marginal cost and opportunity cost.
As an example, we can cite trade between Africa and the United States, where Africa markets agricultural products such as corn and citrus to the US, and the US markets technological products such as computers to Africa.
Therefore, companies will use comparative advantage to acquire goods and services at lower prices than other competitors.
