Answer:
c. 173,500.
Explanation:
If the department completed and transferred 165,000 units, it started and finished 145,000 new units in addition to completing the remaining 60% of the 20,000 unfinished units in the beginning of the period. Aside from that, it also produced 75% of 22,000 additional units.
Using the weighted average method for inventory costing, the number of equivalent units produced by the department is:
[tex]N = 145,000 +(0.60*20,000)+(0.75*22,000)\\N=173,500[/tex]
The department produced 173,500 units.
