Answer:
$40,500
Explanation:
A Companies Contribution Margin is a product's price minus all associated variable costs, this final value gives the products incremental profit earned for each unit sold. Therefore in this scenario, the Contribution Margin for the company is as follows
(4,500 * $20) - (4,500 * $11)
$90,000 - $49,500
$40,500
Therefore the final Contribution Margin for the company is $40,500 dollars.
 
        
             
        
        
        
Answer:
$12,015 approx.
Explanation:
To calculate present value of a future amount, the future amount is discounted at the rate of interest for the period of investment, which reveals present value as on today. The technique is referred to as discounting technique.
Suppose P denote the amount invested today, which when matured after period of two years yields $13500. Following formula is used for calculating the money invested:

wherein, A = Amount 
               P = Principal 
                R = Rate of interest
                n = number of years

13,500 = 1.1236 P
⇒ P = 12,015 Approx.
Thus, $12015 is required to be deposited today so as to yield $13,500 after 2 years compounded at 6% per annum rate of interest. 
 
        
                    
             
        
        
        
The correct answer is B; Taxing the sellers of the product.
Further Explanation:
The seller cannot be taxed for the product. The product makers were already taxed first by the government so they can't tax the product again. Spillover benefits can be both positive and negative. 
By taxing the seller of the product the government is not approaching the socially optimal level. Many times the costs of the spillover may affect a third party and can cause extra costs to someone not even directly related to the product.
