Answer:
$590
Explanation:
Under LIFO Method, the cost of good sold equals to
= Purchase units on Nov 10 × cost per unit + Inventory on Nov 1 × cost per unit
= 20 units × $20 + 10 units × $19
= $400 + $ 190
= $590
Since the firm has sold 20 units on Nov 17, so out of which 20 units sold at a price of $20 and then 10 units was sold on Nov 4 which is to be recorded at $19 from Nov 1 inventory
