Answer:
b) $124
Explanation:
FIFO means first in, first out. Under this principle, goods that were purchased or produced earlier will be the first ones on sale.
The value of the goods sold in our case will be as follows.
The first ten items @ $10: 10X10 =$100
Two items to make 12@ $12: 2x12=$24
Total cost: $100+$24= $124
