Answer:
The cost of goods for the units sold is 15600
Step-by-step explanation:
To get the cost of goods for the units sold, first we must see which units we have to use to make this calculus.
If we use FIFO, first we have to take the units in inventory, then the new ones. So, the 700 units sold are;
400 units at cost $21=8400 (inventory)
300 units at cost $24=7200
Total= 8400+7200=15600
