Answer:
1. Cost of Direct materials in September
= Opening stock of materials + Purchases - Closing stock
= 110,000 + 200,000 - 120,000
= $190,000
2. Total manufacturing cost in September:
= Direct material + Direct labor + Manufacturing overhead
= 190,000 + 110,000 + 365,000
= $665,000
3. Cost of good manufactured:
= Total manufacturing cost + Beginning work in process - Ending work in process
= 665,000 + 60,000 - 90,000
= $635,000
