Answer:
$136
Explanation:
Date Transaction Units Cost Total
3 Purchase 5 $20 $100
10 Sale 3
17 Purchase 10 $24 $240
20 Sale 6
23 Sale 3
30 Purchase 10 $30 $300
using the first in, first out method, the COGS is calculated based on the oldest price of the units in merchandise inventory:
6 units were sold on May 20th, 2 of them costed $20 (May 3rd purchase) per unit = $40, while 4 of them costed $24 (May 17th purchase) = $96. Total COGS = $40 + $96 = $136.
