Come-Clean Corporation produces a variety of cleaning compoundsand solutions for both industrial and household use. While most ofits products are processed independently, a few are related, suchas the company’s Grit 337 and its Sparkle silver polish.

Grit 337 is a coarse cleaning powder with many industrial uses.It costs $1.60 a pound to make, and it has a selling price of $7.20a pound. A small portion of the annual production of Grit 337 isretained in the factory for further processing. It is combined withseveral other ingredients to form a paste that is marketed asSparkle silver polish. The silver polish sells for $5.00 perjar.

This further processing requires one-fourth pound of Grit 337per jar of silver polish. The additional direct variable costsinvolved in the processing of a jar of silver polish are:

Other ingredients	$	0.55
Direct labor		1.44
Total direct cost	$	1.99

Overhead costs associated with processing the silver polishare:

Variable manufacturing overhead cost		25	% of direct labor cost
Fixed manufacturing overhead cost (per month):
Production supervisor	$	3,200
Depreciation of mixing equipment	$	1,500

The production supervisor has no duties other than to overseeproduction of the silver polish. The mixing equipment isspecial-purpose equipment acquired specifically to produce thesilver polish. It can produce up to 11,500 jars of polish permonth. Its resale value is negligible and it does not wear outthrough use.

Advertising costs for the silver polish total $2,800 per month.Variable selling costs associated with the silver polish are 5% ofsales.

Due to a recent decline in the demand for silver polish, thecompany is wondering whether its continued production is advisable.The sales manager feels that it would be more profitable to sellall of the Grit 337 as a cleaning powder.
