Final answer:
Receiving equipment decreases the Encumbrances account and increases the Expenditures account in governmental accounting when the equipment had a prior purchase order.
Step-by-step explanation:
The student asked about the effect of receiving equipment on the Encumbrances and Expenditures accounts in governmental accounting. When equipment is received that had a prior purchase order, the Encumbrances account is decreased because the amount previously set aside for the purchase is no longer needed to obligate. The Expenditures account is increased to recognize the actual outflow of economic resources. Therefore, the correct answer is: Encumbrances Decrease, Expenditures Increase.
