A majority of inventory owned by Deere & Company and its U$.$S$.$ equipment subsidiaries are valued at cost$,$ on the "last$-$in$,$ first$-$out" $($LIFO$)$ basis. Remaining inventories are generally

valued at the lower of cost$,$ on the "first$-$in$,$ first$-$out" $($FIFO$)$ basis, or net realizable value. The value of gross inventories on the LIFO basis at November $1,2020$ and November $3,2019$

represented $52$ percent and $55$ percent, respectively, of worldwide gross inventories at FIFO value. The pretax favorable income effect from the liquidation of LIFO inventory during $2020$

was $$33$ million. If all inventories had been valued on a FIFO basis, estimated inventories by major classification at November $1,2020$ and November $3,2019$ in millions of dollars would

have been as follows:

a$.$ At what dollar amount are Deere's inventories reported on its $2020$ balance sheet?

b$.$ At what dollar amount would inventories have been reported on Deere's $2020$ balance sheet had it used FIFO inventory costing?

$ million

c$.$ What cumulative effect has the use of LIFO inventory costing had, as of year$-$end $2020,$ on its pretax income compared with the pretax income it would have reported had it used FIFO
