Castillo Chemical has spent $239,000 to refine 71,000 gallons of acetone, which can be sold for $2.70 a gallon. Alternatively, Castillo Chemical can process the acetone further. This processing will yield a total of 61,000 gallons of lacquer thinner that can be sold for $3.40 a gallon. The additional processing will cost $0.60 per gallon of lacquer thinner. To sell the lacquer thinner, Castillo Chemical must pay shipping of $0.19 a gallon and administrative expenses of $0.11 a gallon on the thinner.
