Doggi Chew Company uses a traditional product costing system to assign overhead costs uniformly to all products. To meet government regulations and to assure dogs of safe, sanitary, and nutritious food, Doggi Chew engages in quality control. Doggi Chew assigns its quality-control overhead costs to all products at a rate of 15% of direct-labor costs. Its direct-labor cost for the month of February for its puppy food product line is $30,000. Doggi Chew is going to change its costing method to activity-based costing.
