Pharoah Company began operations on January $1,2019,$ adopting the conventional retail inventory system. None of the company's

merchandise was marked down in $2019$ and, because there was no beginning inventory, its ending inventory for $2019$ of

$$38,700$ would have been the same under either the conventional retail system or the LIFO retail system.

On December $31,2020,$ the store management considers adopting the LIFO retail system and desires to know how the December $31,$

$2020,$ inventory would appear under both systems. All pertinent data regarding purchases, sales, markups, and markdowns are shown

below. There has been no change in the price level.

Determine the cost of the $2020$ ending inventory under both $($a$)$ the conventional retail method and $($b$)$ the LIFO retail method. $($Round

ratios for computational purposes to $2$ decimal place, e$.$g$.78\mathrm{.}72\%$ and final answers to $0$ decimal places, e$.$g$.28,987.)$
