Flora Perfume Company manufactures two perfume products in a joint process. In July, raw materials costing $50,000 were processed at a conversion cost of $80,000. The joint process resulted in 10 litres of product A and 15 litres of product B. Product A can be sold for $2 per millilitres, and product B can be sold for $1.5 per millilitres.
