Troy Engines, Ltd., manufactures a variety of engines for use in heavy equipment. The company has always produced all of the necessary parts for its engines, including all of the carburetors. An outside supplier has offered to sell one type of carburetor to Troy Engines, Ltd., for a cost of $32 per unit. To evaluate this offer, Troy Engines, Ltd., has gathered the following information relating to its own cost of producing the carburetor internally:

Fixed manufacturing overhead, allocated		13		202,800
Total cost	$	42	$	655,200

*40% supervisory salaries; 60% depreciation of special equipment (no resale value).
