Answer:
The weighted average unit cost after the October 22 purchase is $15.50
Explanation:
Under the weighted average method of inventory valuation, the closing inventory is valued at weighted average cost.
It can be calculated as follow
Weighted average unit cost = Inventory Balance / Numbers on units in Inventory
_________________________________ Balance

Oct.13 _Sale______280__ $14 __$3,920_( 200__$2,800__ $14 )
Oct.22 _Sale_____ 600__ $16 __$9,600_( 800__$12,400__$15.5 )
