The inventory cost flow assumption that generally best matches the physical flow of inventory is: Weighted-average. Lower of cost and net realizable value. FIFO. LIFO.

FIFO

Explanation:FIFO(FIRST IN FIRST OUT) is a term used in inventory management to describe the way in which means the first finished products or raw materials or WIP(work in process) received must be released or used up before the later once.

FIFO is the best inventory cost flow assumption that generally best matches the physical flow of inventory, and it is the best approach to ensure that materials are effectively used and ensure that losses due to spoilage caused by expiry date is reduced etc.

the investment was $14,174.196

explanation:

a lump sum means that the father of the example made one deposit and leave it be.

we need to know the value of a capital that generated at 4.05% per year during 28 years the sum of $48,613.24

now clearing the formula to solve for capital we got:

and we reach the answer investment = $14,174.20
