SRN is an architectural firm that designs and builds buildings prices each ob on a cost plus 20% basis Overhead costs in 2017 are $5, 580,000. SRN's simple costing system allocates overhead costs to its jobs based on number o obs. There were three jobs in 2017. One customer, Travis, has complained that the cost and price of its building in Chicago was not competitive. As a result, the controller has initiated a detailed review of the overhead allocation to determine if overhead costs should be charged to jobs in proportion to consumption of overhead resources by jobs. She gathers the following information. Requirement 1. Compute the overhead allocated to each project in 2017 using the simple costing system that allocates overhead costs to jobs based on the number of jobs. Determine the formula needed to calculate overhead using the simple costing method and then calculate the overhead rate for 2017. (Round your answer to the nearest dollar.) Requirement 2. Compute the overhead allocated to each project in 2017 using department overhead cost rates. Determine the formula used to calculate the cost driver rates: The 2017 department overhead cost rates by department are as follows
