Answer:
30 units at a cost of $14,80
Explanation:
The table shows purchases sales and balance with its corresponding number of units and cost. Before Patricia sold 30 units, she had 64 units available but not all of them cost her the same. The FIFO inventory method is "First in First out" which means Patricia is going to sell the first units she bought, if she needs more then she goes to the second purchase and so on.
So, if she sold 30 unit then she is going to use the first 20 units she bought at 11$ ($0,55 per each unit), but she is missing 10, then, she is going to take 10 units from the second purchase of 26 units at $10 ($0,38 each unit).
To know the cost of goods sold we need to multiply each unit sold by its cost per unit:
20 units x $0,55 = $11
10 units x $0,38= $3,8
Then we add:
$11+$3,8= $14,80. This is the total cost of goods sold (if we assume $ 11 was the total cost for 20 units and $10 was the total cost for 26 units)
