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

metallurgy is your answer

the "study of metals and the process of refining ("

note that it says metal. metallurgy has the word "metal" in it, and so is most likely your answer (and is your answer).
