Cantrell Company has already manufactured 20,000 units of Product A at a cost of $20 per unit. The 20,000 units can be sold at this stage for $500,000. Alternatively, the units can be further processed at a $300,000 total additional cost and be converted into 4,000 units of Product B and 8,000 units of Product C. Per unit selling price for Product B is $75 and for Product C is $50. Prepare an analysis that shows whether the 20,000 units of Product A should be processed further or not.
