Auerbach Enterprises manufactures air conditioners for automobiles

Auerbach Enterprises manufactures air conditioners for automobiles and trucks manufactured throughout 
North America. The company designs its products with flexibility to accommodate many makes and 
models of automobiles and trucks. The company’s two main products are MaxiFlow and Alaska. 
MaxiFlow uses a few complex fabricated parts, but these have been found easy to assemble and test. 
On the other hand, Alaska uses many standard parts but has a complex assembly and testing process. 
MaxiFlow requires direct materials costs which total $135 per unit, while Alaska’s direct materials 
requirements total $110 per unit. Direct labor costs per unit are $75 for MaxiFlow and $95 for Alaska.
Auerbach Enterprises uses machine hours as the cost driver to assign overhead costs to the air 
conditioners. The company has used a company-wide predetermined overhead rate in past years, but 
the new controller, Bennie Leon, is considering the use of departmental overhead rates beginning with 
the next year.
The following planning information is available for the next year for each the four manufacturing 
departments within the company:
