We can then calculate the difference between the two methods by subtracting one cell from the other to get the absolute difference and then dividing the absolute difference by the FIFO amount to get the percentage difference. Let$$s first consider the journal entries that would be necessary to move from FIFO to weighted average $($assuming that the $2021$ books are still open$)$: $*$using the information provided in the excel file. $1.$ What would be the adjusting journal entry for the change in inventory methods prior to $2021?2.$ What would be the adjusting journal entry for the change in inventory methods in $2021?$
