Which of the following is a disadvantage of the nted-average method compared to the FIFO process-costing method? O A) FIFO is computationally simpler B) FIFO provides better management information for planning and control purposes C) when unit cost per input prices fluctuate markedly from month to month, its per unit cost is less representative than FIFO D) the information it provides about changes in unit prices from one period to the next is less useful than the information provided by FIFO Transferred-in costs are treated as if they are A) conversion costs added at the beginning of the process B) costs of beginning inventory added at the beginning of the process C) direct labor costs added at the beginning of the process D) a separate direct material added at the beginning of the process
