Tamarisk Company produces two products: MB-R and MB-X. Currently, Tamarisk allocates overhead based on direct labour hours. Overhead is estimated at $392,000. The cost accountant realizes that there are some differences in how resources are being used in producing these two components and is considering the use of ABC to allocate overhead. She determines that overhead is caused by testing and inspections, $108,000; machine setup, $72,000; machine stamping, $160,000; and plant maintenance, $52,000. Tamarisk estimates the following activities related to the overhead costs:

Activity		Cost Driver		MB-R		MB-X
Testing and inspections		Number of testing and inspections		360		360
Machine setup		Number of setups		120		80
Machine stamping		Number of machine hours		21,000		11,000
Plant maintenance		Direct labour hours		1,500		2,500

Use ABC cost hierarchy to classify each activity.

Compute the amount of overhead assigned to each product using the traditional (i.e., direct labour hours) costing method. (Round labor rate per hour to 2 decimal places, e.g. 52.75 and the final answers to 0 decimal places, e.g. 5,275.)
