The following information is available for department x for the month of august: work in process, august 1:
materials $ 8,480
conversion costs $15,900
costs added during august:
materials $29,680
conversion costs $26,500
equivalent units of production (weighted average):
materials 4,240
conversion 5,300
department x's cost per equivalent unit for conversion using the weighted average method would be:
a.$8.00.b.$5.00.c.$3.00.d.$9.00.

a. $8.00

Explanation:

The approach we will use to calculate cost per equivalent unit for conversion using weighted average method consists of the following stages:

1st stage: Add beginning (i.e start of August) conversion cost  with conversion costs incurred during August to get total conversion cost

2nd stage: Then divide total conversion cost upon equivalent units of production (units of production for conversion =5300).

Now, lets compute.

Total conversion cost = $15900+$26500

TCC=$42400

Cost per equivalent unit for conversion= $42400÷5300

CPEUC= $8
