Spin Cycle Architecture uses three activity pools to apply overhead to its projects. Each activity has a cost driver used to allocate the overhead costs to the projects. The activities and related overhead costs are as follows: initial concept formation $40,000; design $300,000; and construction oversight $100,000. The cost drivers and estimated use are as follows. (b) Classify each of these activities as unit-level, batch-level, product-level, or facility-level.
