Blaedon Co. makes ongoing design refinements to lawnmowers that are produced for it by contractors. Blaedon stores the lawnmowers in its own warehouse and sells them at list price, directly to retailers. Blaedon uses the FIFO inventory method. Approximately two-thirds of new lawnmower sales involve trade-ins. For each used lawnmower traded in and returned to Blaedon, retailers receive a $40 allowance regardless of whether the trade-in was associated with a sale of a 2020 or 2021 model. Blaedon’s net realizable value on a used lawnmower averages $25.

At December 31, 2020, Blaedon’s inventory of new lawnmowers includes both 2020 and 2021 models. When the 2021 model was introduced in September 2020, the list price of the remaining 2020 model lawnmowers was reduced below cost. Blaedon is experiencing rising costs.

Required:

2. Considering only the 2021 model lawnmower, explain the impact of the FIFO cost flow assumptions on Blaedon’s 2020:
