Answer:
$2120 (closing inventory)
Step-by-step explanation:
FIFO is first in first out method of stock keeping. So basically here you have the closing inventory of 260 units. So you can take:
50 * 9 = 450
200 * 8 = 1600 (since its FIFO so you sell that stock first which you purchased first after which you are
10 * 7 = 70 left with this - adds up to 260 units )
50 + 200 + 10 = 260 units
$450 + $1600 + $70 = $2120 (closing inventory)
