- What is the total cost of units remaining in ending WIP?

Question

Quizplus · Accepted Answer

To calculate the total cost of units remaining in ending WIP, we need to use the weighted average method, which includes both direct materials and conversion costs. 
Total cost of units to account for = Beginning WIP + Units started in process = $28,200 + $386,600= $414,800 
Unit cost = Total Cost of Units to Account For ÷ Units in Process = $414,800 ÷ 23,000 = $18.043 per unit 
Units in ending WIP = 4,400 
Total cost of units remaining in ending WIP = Unit cost x Units in ending WIP = $18.043 x 4,400 = $79,464
Since the answer options are not exactly matching, the closest answer is B ($94,222), which may not be the exact answer but closest to the calculated amount.
