Inventory Costing Methods$-$Periodic Method

The Luann Company uses the periodic inventory system. The following July data are for an item in Luann's inventory:

$\backslash$table$[[$July$,1,$Beginning inventory,$30,$units @$,$$$9,$per unit$],[,10,$Purchased,$50,$units @$,$$$11,$per unit$],[,15,$Sold,$60,$units,,$],[,26,$Purchased,$25,$units @$,$$$13,$per unit$]]$

Calculate the cost of goods sold for July and ending inventory at July $31$ using $($a$)$ first$-$in$,$ first$-$out, $($b$)$ last$-$in$,$ first$-$out, and $($c$)$ the weighted$-$average cost methods.

Note: Round your cost per unit to three decimal places, if needed. Then round your final answers to the nearest dollar.
