I'm very confused, can you please show your work as to how you calculate the numbers so that I understand the concept. Thanks!! Assume that Disney uses a perpetual weighted average inventory system. During the period, it had two sales. Calculate the average cost per unit on hand as of June 30 when it made its second sale.

Jun 1	Beginning Inventory	10 @ $12
Jun 5	Purchase	10 @ $15
Jun 8	Sale	6 units
Jun 28	Purchase	10 @ $18
Jun 30	Sale	8 units

$13.50 $10 $15.375 $15
