300000/15000
=$20
300000/12000
=$ 25
300000/1000
=$ 300
[15000*10]+300000
150000+300000
450000
[12000*10]+300000
120000+300000
420000
[1000*10]+300000
10000+300000
310000
450000/15000= $ 30
310000/1000

**Total production cost =[unit produced*variable manufacturing cost per unit]+fixed manufacturing overhead
4)under LIFO,method units acquired last are sold first ,so ending inventory in every quarter are left out of initial balance (initial quarter balance)
[5000*30]from quarter 2 +[4000*35] from quarter 3 =150000+140000
=290000
Cost of ending inventory depends on manufacturing cost each quarter as under LIFO ending inventory are left out of units manufactured first.so cost of ending inventory depends on production level in each quarter.
