The Marshall Company has a process cost system. All materials are added when the process is first begun. At the beginning of September, there were no units of product in process. During September, 50,000 units were started; 5,000 of these were still in process at the end of September and were 3/5 finished. The equivalent units of material in September were:

a.40,000.

b.45,000.

c.48,000.

d.50,000

c) 48,000 units

Explanation:

The question is to compute the equivalent units of materials in September for Marshall Company

It is computed as follows:

1) Beginning Equivalent Unit

At the beginning, Units = 0, Percent completed = 0 and Equivalent unit= $0

Equivalent Units  Started ad Completed

2) Started Units= 50,000 units

Units still in process at the end of September = 5000 units

Started and Completed = 50,000 - 5,000 = 45,000

Since the Units completed is 45,000, it means 100% completed equivalent unit is 45,000

3) Closing Equivalent Units

In process = 5,000 units and percent completed is 3/5

Equivalent unit is 3/5 x 5000 = 3000 units

Finally, total equivalent units  for conversion costs in September

= 0 + 45,000 + 3,000

=48,000 units
