The Oahu Audio Company manufactures electronic subcomponents that can be sold as is or can be processed further into "plug-in" assemblies for a variety of intricate electronic equipment. The entire output of subcomponents can be sold at a market price of $2.20 per unit. The plug-in assemblies have been generating a sales price of $5.70 for 3 years, but the price has recently fallen to $5.30 on assorted orders. JanetOh, the vice president of marketing, has analyzed the markets and the costs. She thinks that production of plug-in assemblies should be dropped whenever the price falls below $4.70 per unit. However, at the current price of $5.30, the total available capacity should currently be devoted to producing plug-in assemblies

She has cited the following data:

Data table

	Subcomponents
Selling price, after deducting relevant selling costs			$2.20
Direct materials	$1.10
Direct labor	0.30
Manufacturing overhead	0.60
Cost per unit			2.00
Operating profit			$0.20
	Plug-In Assemblies
Selling price, after deducting relevant selling costs			$5.30
Transferred-in variable cost for subcomponents	$1.40
Additional direct materials	1.45
Direct labor	0.45
Manufacturing overhead	1.20	*
Cost per unit			4.50
Operating profit			$0.80
* For additional processing to make and test plug-in assemblies

Direct-materials and direct-labor costs are variable. The total overhead is fixed; it is allocated to units produced by predicting the total overhead for the coming year and dividing this total by the total hours of capacity available. The total hours of capacity available are 600,000. It takes 1 hour to make 60 subcomponents and 2 hours of additional processing and testing to make 60 plug-in assemblies.

Requirements

1.	If the price of plug-in assemblies for the coming year is to be $5.30, should sales of subcomponents be dropped and all facilities devoted to the production of plug-in assemblies? Show your computations.
2.	Show the lowest possible price for plug-in assemblies that would be acceptable.
3.	Suppose 40% of the manufacturing overhead is variable with respect to processing and testing time. Repeat numbers 1 and 2. Is there any change? If so, how?

Requirement 1. If the price of plug-in assemblies for the coming year is to be $5.30, should sales of subcomponents be dropped and all facilities devoted to the production of plug-in assemblies? Show your computations. Begin by calculating the total contribution margin assuming the company only produces and sells subcomponents and the total contribution margin assuming the company only produces and sells plug-in assemblies. Start by selecting the labels. (Round amounts to the nearest cent.)
