Answer:
total cost of goods sold = $78,520
Step-by-step explanation:
Inventory Purchases Sales
May 1 1,300 units at $36
May 10 650 units at $38
May 12 910 units
Cost of goods sold = (650 x $38) + (260 x $36) = $34,060
May 20 585 units at $40
May 14 780 units
Cost of goods sold = (585 x $40) + (195 x $36) = $30,420
May 31 390 units
Cost of goods sold = 390 x $36 = $14,040
total cost of goods sold = $34,060 + $30,420 + $14,040 = $78,520
