Answer:
17,750 units
Explanation:
Calculation of equivalent units for conversion costs - FIFO
To finish Opening Work in Process  (5,000 units x 35%)       1,750
Started and Completed [(19,000 units  - 5,000 units) x 100%]  14,000
Ending Work in Process (4,000 units x 50%) Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 2,000
Equivalent units of production                           17,750
therefore,
the equivalent units for conversion costs would be 17,750 units
