Purple Company produced 50 defective units last month at a per-unit variable manufacturing cost of $30. The defective units were discovered before they were shipped out of the factory. Purple can sell them "as is" for an additional $20 per unit or can rework them at a cost of $15 and sell them at the regular price of $50. In this scenario, the $30 per unit manufacturing cost is a cost. Maroon Company spends $500 each month to make a batch of goo.
