1. Apollonia Dental Services is part of an HMO that operates in a large metropolitan area. Currently, Apollonia has its own dental laboratory to produce two varieties of porcelain crownsall porcelain and porcelain fused to metal. The unit costs to produce the crowns are as follows:

   	All Porcelain				Porcelain Fused to Metal
   Direct materials		$190				$80
   Direct labor		50				20
   Variable overhead		25				5
   Fixed overhead		60				40
   Total		$325				$145

   Fixed overhead is detailed as follows:

   Salary (supervisor)	$30,000
   Depreciation	8,000
   Rent (lab facility)	22,000

   Overhead is applied on the basis of direct labor hours. The rates above were computed using 8,000 direct labor hours. No significant non-unit-level overhead costs are incurred.

   A local dental laboratory has offered to supply Apollonia all the crowns it needs. Its price is $265 for all-porcelain crowns and $145 for porcelain-fused-to-metal crowns; however, the offer is conditional on supplying both types of crownsit will not supply just one type for the price indicated. If the offer is accepted, the equipment used by Apollonia's laboratory would be scrapped (it is old and has no market value), and the lab facility would be closed. Apollonia uses 2,500 all-porcelain crowns and 1,000 porcelain-fused-to-metal crowns per year.
