Final answer:
The unexpended resources from a sales tax increase for schools would be displayed as a surplus fund balance, indicating tax revenue exceeded school expenditures.
Step-by-step explanation:
The unexpended resources from the proposed sales tax increase to be used for local schools would be displayed as surplus fund balance. A surplus refers to the amount of money that remains when the government collects more in taxes than it spends on public services like education. The presence of a surplus indicates that the sales tax revenue exceeded the expenditures for the schools, and these additional funds are typically earmarked for specific future use or savings within the school district's budget.
