Traditionally Manufacturing Overhead (M/O) cost is applied on the basis of direct labor hours (DLH); estimated M/O cost is $ 5,757,500 and the estimated DLH is $12,250 for the most recent period.The team decided to replace traditional plantwide costing system to activity-based costing system. There are 3 activity cost pools which represent 3 activity areas at the plant. Direct Labor wage rate is $ 30 per hour. Compute total cost per unit (for lambda and gamma) using activity-based approach. (round your numbers).arrow_forward
