Why The weighted average method counts prior-period work and costs in BWIP as if they belong to the current period; thus, the unit cost is obtained by dividing the sum of the costs in BWIP and the current-period costs by the weighted average equivalent output. The resulting unit cost is a blend of the prior-period u cost and the actual current-period unit cost. The valuation of cost of goods transferred out is simplified as it is the total unit cost multiplied by the units completed. Required average method(Step 3). 1. Calculate the unit cost for May, using the weighted 2. Calculate the cost of goods transferred out and the cost of EWIP(Step 4). Also reconcile the costs assigned with the costs to account for(Step 5). 3. What if you were asked to show that the weighted average unit cost for material l of the April unit materials cost and the May unit materials cost
