Suppose you work for a company that sells computers and that you have been asked to oversee doing a physical count and valuation of the inventory at year end. You determine the value of inventory on hand to be $23,500 yet according to the Inventory account in the ledger the balance should be $35,000. Required: Using a minimum of 100 words, give two reasons that could explain why the balances are not the same and what journal entry would need to be recorded in the books
