The correct answer is: C= $440
Step-by-step explanation:
Giving the following information:
sales - $830; 
raw materials inventory, beginning - $50,
raw materials inventory, ending - $40;
purchases of raw materials - $150; 
direct labor - $140
manufacturing overhead - $160; 
administrative expenses - $120; 
selling expenses - $150; 
work in process inventory, beginning - $30;
work in process inventory, ending - $50; 
finished goods inventory, beginning - $80; 
finished goods inventory, ending - $100.
Cost of goods manufactured= beginning work in process + direct materials + direct labor + manufacturing overhead - ending work in process
Cost of goods manufactured= 30 + (50 + 150 - 40) + 140 + 160 - 50= $440
