Using the FIFO method, calculate the following:

1-a. Costs per equivalent unit. (Round your answers to 4 decimal places.)

1-b. Cost of goods completed and transferred out. (Do no round your intermediate calculations. Round your final answer to the nearest whole dollar.)

1-c. Costs remaining in the Work-in-Process Inventory account. (Do no round your intermediate calculations. Round your final answer to the nearest whole dollar.)

2. Assume that you are the companys controller. The production departments February equivalent unit cost is higher than expected. If the manager of the first department asks you to do him a favor by increasing the ending inventory completion percentage from 30 to 50% to lower the unit costs, how much would unit cost be affected by this request? (Round your answer to 4 decimal places.)
