(Do not round intermediate calculations. Round your answers to 2 decimal places.) b. Compute the unit costs for the two products V-1 and V-2 using the proposed ABC system at Upriver. (Do not round intermediate calculations. Round your answers to 2 decimal places.) Unit Cost V-1 V-2 a. Using current costing system Using proposed ABC system b. Required: a. Upriver currently applies overhead on the basis of machine hours. What is the predetermined overhead rate for the month? (Round your answer to 2 decimal places.) b.
