The Mallak Company produced three joint products at a joint cost of $140,000. Two of these products were processed further. Production and sales were:

Product	Weight		Sales			Additional Processing Costs
P	320,000	lbs.	$	280,000		$	220,000
Q	120,000	lbs.		50,000			-0-
R	120,000	lbs.		220,000			120,000

Assume Q is a by-product and Mallak uses the cost reduction method of accounting for by-product cost. If estimated net realizable value is used, how much of the joint costs would be allocated to product R?
