Solution :
 Alternative A Alternative B Alternative C
Annual fixed cost 105000 126000 82000
Variable fixed cost 24 25 37
a). We have to find out the Break even quantity :
 Break Even quantity for A 

 

 = 3750 units
 Break Even quantity for B 

 

 = 4666 units
 Break Even quantity for C 

 

 = 5466 units
Therefore, Alternate A has the lowest Break Even quantity.
b). Now, 


 = 280,000 - 105,000
 = 175,000

 = 270,000 - 126,000
 = 144,000

 = 150,000 - 105,000
 = 45,000 
Thus, alternate A has the highest amount of profit.
c). 

Units of the target profit for A 

 = 5535 units
Units of the target profit for B 

 = 6517 units
Units of the target profit for C 

 = 8799 units
Thus Alternative A will require the lowest volume of the output.
