LIFO Pre-2020 2020 FIFO $2,960 830 $3,790 Average Cost $2.700 520 $3,220 580 $3,020 3. Assume that Weihrich used FIFO before 2021, and then in 2021 decided to switch to LIFO cost. Weihrich's records of inventory purchases and sales are not available for several previous years. Therefore, the pre-2020 LIFO information ($2.440) is not available. However, Weihrich does have the information needed to apply LIFO on a prospective basis beginning in 2020. Prepare the journal entry to record the change in accounting principle.
