An Exxon petrochemical factory produces two products, L and M, as a result of a particular joint process. Both products are sold to manufacturers as ingredients for assorted chemical products. Product L sells at split-off for $.25 per gallon; M sells for $.30 per gallon. Data for April follow:

Joint processing cost $1,600,000

Gallons produced and sold

L 4,000,000

M 2,500,000

Suppose that in April the 2,500,000 gallons of M could have been processed further into Super M at an additional cost of $165,000. The Super M output would be sold for $.36 per gallon. Product L would be sold at split-off in any event.

Should M have been processed further in April and sold as Super M? Show your computations.
