Current Attempt in Progress

Concord Computer Shop began operations on June $1$ and uses a perpetual inventory system. During June, the company had the following purchases and sales for its Model $10$ Fastback Computer System:

$\backslash$table$[[$Date$,$Purchases,Sales $($Units$)],[$Units$,$Unit Cost$],[$June$,1,5,$$$2000,],[5,,,4],[9,10,$$$3100,],[16,,,5]]$

Using the weighted average cost formula, the balance in ending inventory on June $30$ is

$$ $$15300.$

$$23500.$

$$18000.$

$$22400.$
