Answer:
 a. 29%
Explanation:
Given that
Contribution margin = $55,900
Sales = $190,000
The computation of contribution margin ratio is shown below:-
Contribution margin ratio = Contribution margin ÷ Sales
= $55,900 ÷ $190,000
= 29%    
Therefore for computing the contribution margin ratio we simply divide sales by contribution margin ratio.
 
        
             
        
        
        
Answer:
The incomplete part of the question is "Using a cap-and-trade system of tradable emission allowances will eliminate half of the sulfur dioxide pollution at a cost of $1 million per year. If the permits are not tradable, what will be the cost of eliminating half of the pollution? If permits cannot be traded, then the cost of the pollution reduction will be $1 million per year." The full question is attched as picture as well
 
1) Tradable permit system
Then lower MAC firm will abate the all pollution units
Then as MAC1 = $250, MAC2 = $275
Firm 1 = Consolidated electric
Firm 2 = Commonwealth utility
Then 1 will sell all permits to 2, at a price between $250 & $275.
So total cost of abatement of 20 units = MAC1 * 20
= $250 * 20  Unit
= $5,000
2) Non-tradable permits
Total cost = MC1*10 + MC2*10
= $2,500 + $2,750
= $5,250
