June 2 sale of 900 items….. 3.20 each because those are the only ones in inventory at the time of sale.

June 6 sale of 2400 items…. 3.10 each because the purchase on June 3 was sufficient to handle this sale (LIFO)

June 9 sale of 1500 items… 3.30 from June 7 purchase

June 10 sale of 600 items… aha! tricky one…

Let’s figure this one out… we have on hand by this time…

300 @ 3.20 from June 1

900 @ 3.10 from June 3

300 @ 3.30 from June 7…. SO… we sell 600 on June 10 from existing inventory… 300 @ 3.30 (LIFO) and 300 @ 3.10, leaving the 300 from June 1 and 600 from June 3 purchases…

Then we have June 18 sale of 2100 items from the June 15th purchase @ 3.40, leaving 600 @ 3.40.

And the final sale of 450 items from the June 22nd purchase, which leaves 300 @ 3.50.

Okay, so, now where does that leave us?

300 from the June 1 existing inventory @ 3.20

600 from the June 3 purchase @ 3.10

600 from the June 15th purchase @ 3.40

300 from the June 22 purchase @ 3.50

Just multiply that out, and that’s your ending inventory.

What, you thought I was going to do it all?? 😉
