Inventory Costing Methods$-$Periodic Method

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

July $1$ Beginning inventory $15,330$ units @ $$3$ per unit

$10$ Purchased $15,350$ units @ $$4$ per unit

$15$ Sold $15,360$ units @

$26$ Purchased $15,325$ units @ $$5$ 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. Round your final answers to the nearest dollar.
