In a perpetual average cost system a new weighted-average unit cost is calculated each time additional units are purchased.
Option B is correct
Explanation:
"Average" represents the mean expense of production items from the sale time below the perpetual method. This marginal cost is compounded by the numbers of distribution units, deducted from the stock in the possession and debited to the Expense of Items Sold balance.
Divide the prices of goods available on the market by the amount of available on the market to be using the median weighted practice, which results in the total average cost of units. The cost of the product available on the market is the amount of the original production and net sales in this estimate.
