Adelberg Company has two products: A and B. The annual production and sales of Product A is 1,900 units and of Product B is 1,300 units. The company has traditionally used direct labor-hours as the basis for applying all manufacturing overhead to products. Product A requires 0.4 direct labor-hours per unit and Product B requires 0.7 direct labor-hours per unit. The total estimated overhead for next period is $101,075. The company is considering switching to an activity-based costing system for the purpose of computing unit product costs for external reports. The new activity-based costing system would have three overhead activity cost pools--Activity 1, Activity 2, and Order Size--with estimated overhead costs and expected activity as follows:
Expected Activity
Activity Cost Pools Estimated Overhead Costs $ Product A Product B Total

Activity 1 $31,031 1,000 300 1,300
Activity 2 22,249 1,600 300 1,900
Order size 15,476 200 200 400
Total $ 68,756 (Note: The Order Size activity cost pool's costs are allocated on the basis of direct labor-hours.) The predetermined overhead rate under the traditional costing system is closest to:________
a. $11.71 per DLH
b. $38.69 per DLH
c. $171.89 per DLH
d. $23.87 per DLH
