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 $41, 500; design $308,000; and construction oversight $124, 600. The cost drivers and expected use are as follows. Compute the predetermined overhead rate for each activity. (Round overhead rate per square foot to 2 decimal places, e.g. 2.25 and all other answers to O decimal places, e.g. 1, 225.) Classify each of these activities as unit-level, batch-level, product-level, or facility-level
