Answer:100
Explanation:
The following information can be gotten from the question:
Cost for 10 sofas = $2500 
Cost for 12 sofas = $2760.
Average Cost = Total Cost/Quantity
2500 / 10 = $250 and
$2760 / 12 = $230
The average cost for 12 sofas will be $230
Marginal cost is the change in total cost divided by the change in quantity. This will be:
= ( 2760 - 2500 )/( 12 - 10 ) 
= 260/2
= 130
The difference between the average cost per sofa for 12 sofas and the marginal cost of the 12th sofa will be:
=230 - 130 
= 100

Answer:
100 times per year
Explanation:
Data provided in the question:
Annual Demand , D = 320,000 boxes
Cost of storing one box, C = $10 
Plant set up cost for production, c = $160
Now,
The optimal ordering quantity = 
or
The optimal ordering quantity = 
or
= 3200
Therefore,
Number of timer in year company produce boxes =  
=  
= 100 times per year
