Answer:
c. 173,500.
Step-by-step 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:
![N = 145,000 +(0.60*20,000)+(0.75*22,000)\\N=173,500](https://img.qammunity.org/2021/formulas/business/college/ka2tyn445g7ajd8khbm60027sy5yyu27q5.png)
The department produced 173,500 units.
