27. To calculate the equivalent units of production, the number of physical units is multiplied by the percentage
of completion.
28. If changes occur in the prices of the manufacturing inputs from one period to the next, then FIFO produces a
more accurate unit cost than does the weighted average method.
29. Different percentage completion figures for manufacturing inputs pose a problem for the calculation of
equivalent units, unit cost, and valuation of ending work in process.
30. The solution for different percentage completion figures for manufacturing inputs is to calculate equivalent
units for one category of manufacturing input.
31. The usual approach is to treat transferred-in goods as a separate conversion category when calculating
equivalent units.
32. Since FIFO excludes prior-period work and costs, it is necessary to create three categories of completed
units.
33. FIFO assumes that units in beginning work in process are completed first, before any new units are started.
34. Under the FIFO method, for the beginning work-in-process units, the total associated manufacturing costs
are the sum of the prior-period costs plus the costs incurred in the current period to finish the units.
