Answer:
The amount that the Town of Harmon currently have available to spend for street maintenance supplies is $20,000.
Step-by-step explanation:
From the question, we can obtain the following:
Amount appropriated for street maintenance supplies = $90,000
Outstanding encumbrances for street maintenance supplies = $40,000
Expenditures incurred for street maintenance supplies = $30,000
Therefore, we have:
Amount currently available to spend for street maintenance supplies = Amount appropriated for street maintenance supplies - Outstanding encumbrances for street maintenance supplies - Expenditures incurred for street maintenance supplies = $90,000 - $40,000 - $30,000 = $20,000
Therefore, the amount that the Town of Harmon currently have available to spend for street maintenance supplies is $20,000.
