Answer:
152,600 units
Step-by-step explanation:
Weighted average costing adds the value of beginning inventory in the period cost to calculate the average cost per unit.
According to this method the equivalent units formula is as follow
Equivalent Units = Unit completed and transferred to Finished goods + Units in Work in Process x Completion percentage
Units Completed in the period = 37,000 + 122,000 - 32,000 = 127,000
Equivalent Units = 127,000 + (32,000 x 80%) = 152,600 units
