Explanation:
a. The average cost method is used by finding out the average cost of all available inventory just before a 1st sales (total purchase cost /total quantity available before sales).In this case it is ($4,440/1,070)= $4.14953271. 1st and 2d sales is then carried out based on this price. The price changes as new purchases are made. if this is done using excel the result will be as file attached;
