In a perpetual average cost system: a. The average is determined by dividing the total number of units sold by the cost of units purchased during the period. b. A new weighted-average unit cost is calculated each time additional units are purchased. c. The cost allocated to ending inventory is generally the same as it would be in a periodic inventory system. d. The moving-average unit cost is determined following each sale.

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.
