Results are below.

Explanation:

First, we need to calculate the direct material used:

Direct material used= beginning inventory + purchases - ending inventory

Direct material used= 27,000 + 104,000 - 30,000

Direct material used= $101,000

Now, the cost of goods manufactured:

cost of goods manufactured= beginning WIP + direct materials + direct labor + allocated manufacturing overhead - Ending WIP

cost of goods manufactured=  39,000 + 101,000 + 129,000 + 104,000 - 49,000

cost of goods manufactured= $324,000

Finally, the cost of goods sold:

COGS= beginning finished inventory + cost of goods manufactured - ending finished inventory

COGS= 79,000 + 324,000 - 59,000

COGS= $344,000
