Compute the cost assigned to ending inventory using

(a) fifo,
(b) lifo,
(c) weighted average, and
(d) specific identification.
for specific identification, units sold consist of 620 units from beginning inventory, 210 from the february 10 purchase, 120 from the march 13 purchase, 140 from the august 21 purchase, and 390 from the september 5 purchase. (round your average cost per unit to 2 decimal places.)

Brody corp. uses a process costing system in which direct materials are added at the beginning of the process and conversion costs are incurred uniformly throughout the process. beginning inventory for january consisted of 1,050 units that were 65% completed. 10,900 units were started into the process during january. on january 31, the inventory consisted of 500 units that were 50% completed. what would be the equivalent units for direct materials cost using the weighted average method?
