A distinct feature of the FIFO process$-$costing method is that the $\_\_\_\_\_\_\_\_.$ Group of answer choices work done on beginning inventory before the current period is blended with the work done during the current period in the calculation of equivalent units work done on ending inventory is kept separate from the work done during the current period in the calculation of equivalent units and is usually not included in the calculation work done on beginning inventory before the current period is kept separate from the work done during the current period in the calculation of equivalent units FIFO process$-$costing method is only minimally different from the weighted$-$average process$-$costing method
