Using the weighted-average method, the material work in process inventory consists of 10 units that are 85% complete using materials that cost an average of $17.0175 per unit, or $145. Thus, the $25 difference can be accounted for and the two methods reconciled.he difference in the two methods results in $65 less being charged to work in process when the weighted-average method is used than when the FIFO method is used. The $65 is part of the costs transferred to the next department.
