Flow of Inventoriable Costs

--------------------------------------------------------------------------------

Direct materials inventory 8/1/07 $90,000,000
Direct materials purchased $360,000,000
Direct materials used $375,000,000
Total manufacturing overhead $480,000,000
Variable manufacturing overhead $$250,000,000
Total manufacturing costs $1,600,000,000
Work-in-process inventory 8/1/07 $200,000,000
Costs of goods manufactured $1,650,000,000
Finished goods inventory 8/1/07 $125,000,000
Cost of goods sold $1,700,000,000




What formulas do I use to calculate the following?
1. Direct materials inventory 8/31/07
2. Fixed manufacturing overhead costs for August
3. Direct manufacturing labor costs for August
4. Work-in-process inventory 8/31/07
5. Goods available for sale in August
6. Finished goods inventory 8/31/07


I really need to know how to get the formulas for my problem. Thanks

See my reply in this thread as it's the same question. You really need to start thinking of this in terms of the flow of the accounts, which is what it really is, instead of like it's "formulas."
