Njombe Corporation manufactures a variety of products. In the past, Njombe has been using a traditional costing system in which the predetermined overhead rate was 150% of direct labor cost. Selling prices had been set by multiplying total product cost by 200%. Sensing that this system was distorting costs and selling prices, Njombe has decided to switch to an activity-based costing system for manufacturing overhead costs that uses the three activity cost pools listed below. Selling prices are still to be set at 200% of unit product cost under the new system. Information on these cost pools for next year are as follows:

Activity Cost Pool Activity Measure Estimated Activity Estimated Overhead Cost Machine Setups Number of setups 400 $ 150,000 Quality Control Number of inspections 1,500 $ 180,000 Other Overhead Machine hours 30,000 $ 480,000

Information (on a per unit basis) related to three popular products at Njombe are as follows:

Model #19 Model #36 Model #58 Direct material cost $ 400 $ 540 $ 310 Direct labor cost $ 810 $ 600 $ 220 Number of setups 2 3 1 Number of inspections 1 3 1 Number of machine hours 4 8 10
