$18-25.$ WEIGHTED$-$AVERAGE METHOD, ASSIGNING COSTS $($CONTINUATION OF $18-24).$

For the data in Exercise $18-24,$ summarize total costs to account for, calculate cost per equivalent unit for direct materials and conversion costs, and assign costs to units completed $($and transferred out$)$ and to units in ending work$-$in$-$process inventory.

$18-26.$ FIFO METHOD, EQUIVALENT UNITS.

Refer to the information in Exercise $18-24.$ Suppose the assembly division at Quality Time Pieces, Inc. uses the FIFO method of process costing instead of the weighted$-$average method.

Compute equivalent units for direct materials and conversion costs. Show physical units in the first column of your schedule.
