Answer:
a. Cost of goods sold = Sales - Gross profit
Cost of goods sold = $12,755,000 - $5,359,700
Cost of goods sold = $7,395,300
b. Direct Material Cost = Materials purchased - Indirect materials - Materials inventory
Direct Material Cost = $4,251,600 - $185,500 - $298,900
Direct Material Cost = $3,767,200
c. Direct labor cost = Total manufacturing costs for the period - Direct materials cost - Other factory overhead - Indirect labor
Direct labor cost = $8,122,000 - $3,767,200 - $834,900 - $422,600
Direct labor cost = $3,097,300
