The correct answer is D: $1900

Explanation:

Giving the following information:

Sales revenue$ 4,000

Purchases of direct materials$ 400

Direct labor$ 450

Manufacturing overhead $ 620

Operating expenses$ 650

Beginning raw materials inventory$ 200

Ending raw materials inventory$ 180

Beginning work in process inventory$ 320

Ending work in process inventory$ 410

Beginning finished goods inventory$ 250

Ending finished goods inventory$ 200

First, we need to calculate the cost of goods manufactured:

cost of goods manufactured= beginning work in process + direct materials + direct labor + manufacturing overhead - ending work in process

Direct materials= beginning inventory + purchase - ending inventory= 200 + 400 - 180= 420

cost of goods manufactured= 320 + 420 + 450 + 620 - 410= $1400

Now, we can calculate the cost of goods sold:

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

COGS= 250 + 1400 - 200= 1450

Operating income= sales  - COGS - operating expenses

Operating income= 4000 - 1450 - 650= $1900
