The Chinese Teapot Company manufactures plastic and ceramic teapots. The company's western plant has changed from a labor-intensive operation to a robotics environment. As a result, management is considering changing from a direct-labor based overhead rate to an activity-based cost method. The controller has chosen the following activity cost pools and cost drivers for the factory overhead: Expected Overhead Cost Cost Driver Annual Cost Driver Purchase orders $300,000 Number of orders 15,000 orders Set-up costs $200,000 Number of set-ups 5,000 set-ups Testing costs $320,000 Number of tests 8,000 tests Machine maintenance $500,000 Machine hours 25,000 hours REQUIRED: a. Compute the overhead rate for each cost driver. b. An order for 50 ceramic teapots had the following requirements: Number of purchase orders 3 Number of set-ups 20 Number of product tests 7 Machine hours 150 How much overhead would be assigned to this order?
