Periodic Inventory Using FIFO, LIFO, and Weighted Average Cost MethodsThe units of an item available for sale during the year were as follows:Jan. $1$Inventory$19$units at $$30$$$570$Aug. $13$Purchase$18$units at $$32576$Nov. $30$Purchase$9$units at $$34306$Available for sale$46$units$$1,452$There are $18$ units of the item in the physical inventory at December $31.$ The periodic inventory system is used. Determine the inventory cost using the $($a$)$ first$-$in$,$ first$-$out $($FIFO$)$ method; $($b$)$ last$-$in$,$ first$-$out $($LIFO$)$ method; and $($c$)$ weighted average cost method $($round per$-$unit cost to two decimal places and your final answer to the nearest whole dollar$).$a$.$First$-$in$,$ first$-$out $($FIFO$)$$fill in the blank $1$b$.$Last$-$in$,$ first$-$out $($LIFO$)$$fill in the blank $2540$c$.$Weighted average cost$fill in the blank $3$
