Windsor INC. purchased inventory during the month of June as follows:

June 1 129 units at $890

June 10 172 units at $1340

June 15 172 units at $1440

Under LIFO method, likewise the last entered inventory will be available for sale and the inventory at the end of period will be valued at the price at which the inventory first bought i.e $890, therefore the value amounts to 180 units*$890=$160200

Under Average cost method the effect of differential price is distributed over the quantity bough during a period so that the company remains in ineffective condition during the period from the price change

Average cost per unit= (129*$890 +172*$1340+ 172*$1440+129*$1140)/602 units

=$1229.29

and for the 180 units the value amounts to 180*$122.29=$221271.429
