Answer:
the amount of cash flow from operating activities is not affected by the cost flow method.
Step-by-step explanation:
Cost flow method is defined as a method of assigning cost to inventory and cost of goods sold. There are various assumptions that are made to determine the goods still in inventory and those that have been sold.
Average cost flow takes all cost from goods sold from inventory and assigns them to the goods.
In this instance using any cost flow method there will be an outflow of $38 for purchase of the items and an inflow of $30.
