Tamiku [17]

Answer: The cost of goods sold= 5881.75


Step-by-step explanation:

Cost of available  goods = 75x32.97 + 75x33.78 + 150x35.02= $10259.25

Units available= 150 + 75 + 75= 300

Sold units= 175

Ending  inventory= 300-175=125

Value of ending inventory= 125x35.02= $4377.5

Cost of goods sold= cost of available goods – value of ending inventory

Cost of goods sold= 10259.25 – 4377.5= $5881.75
