Larsen company manufactures car seats in its San Antonio plant. Each car seat passes through the Assembly department and the Testing Department. This problem focuses on the Assembly Department. The process-costing system at Larsen Company has a single direct-cost category ( direct materials) and a single indirect-cost category (conversion costs). Direct materials are added at the beginning of the process. Conversion costs are added evenly during the process. When the Assembly Department finishes work on each car seat, it is immediately transferred to Testing.

Larsen Company uses the weighted-average method of process costing. Data for the Assembly Department for October 2009 are:

the physical units are the car seats

1. For each costs category, compute equivalent units in the Assemly Department. Show physical units in the first column of your schedule.

2 For each cost category, summerize total Assembly Department costs for October 2009 and calculate the cost per equivalent unit.

3. Assign total costs to units completed and transferred out and to units in ending work in process.
