Answer:
To calculate the cost of goods sold using cost averaging, we need to determine the average cost per unit based on the given information.
Step 1: Calculate the total cost of the units received:
(30 units * $2.21) + (60 units * $2.20) + (20 units * $2.18) + (50 units * $2.25) = $66.30 + $132.00 + $43.60 + $112.50 = $354.40
Step 2: Calculate the total number of units received:
30 units + 60 units + 20 units + 50 units = 160 units
Step 3: Calculate the average cost per unit:
Total cost of units received / Total number of units received = $354.40 / 160 units = $2.215 per unit (rounded to the nearest cent)
Step 4: Calculate the cost of goods sold:
100 units sold * $2.215 per unit = $221.50
Therefore, the cost of goods sold using cost averaging is $221.50.
