Answer:
Operating income = $2,880
Explanation:
Operating income is calculated by providing cost of goods sold, manufacturing overheads, selling and administrative cost.
Here, cost of goods sold shall be calculated as follows:
Raw materials consumed = Opening inventory + Purchases - Closing inventory = $240 + $450 - $230 = $460
Expenses for manufacturing consumed in work in progress:
= Opening work in process + Manufacturing overheads - Closing work in process
= $360 + $630 - $470 = $520
Opening finished goods will be added and the closing shall be deducted.
Direct labor cost will also be part of cost of goods sold.
Therefore, Operating income shall be
Sales Revenue - Raw material consumed - Expenses of manufacturing - Opening Finished goods + Closing finished goods - Direct labor cost
= $4,500 - $460 - $520 - $350 + $230 - $520 = $2,880
