Answer:
$5000
Explanation:
Since Elm City issued a purchase order for supplies with an estimated cost of $5,000, although when the supplies were received, the accompanying invoice indicated an actual price of $4,950, the amount that Elm should credit to encumbrances outstanding in its general fund after the supplies and invoice were received; is $5000
Notice that encumbrances are set aside funds for a purpose, therefore upon ordering, encumbrances balance would increase, and Elm would have passed the following entry
Dr. Encumbrances...$5000
Cr. Fund Balance.....................$5000
Therefore even if the supply came with a shortfall in amount, in order for Elm City to show that the purpose for making that encumbrance has been met, it has to be liquidated by crediting the Encumbrance account by the full amount of $5000
