Final answer:
The $100,000 gift received by the Western Falls School District is accounted for as a private-purpose trust fund.
Step-by-step explanation:
The $100,000 gift received by the Western Falls School District is accounted for as a private-purpose trust fund. A private-purpose trust fund is created when funds are donated to a government entity or nonprofit organization for a specific purpose or benefit of individuals or organizations outside of the government entity or nonprofit organization itself. In this case, the funds are used to provide a freshman scholarship to the valedictorian of the high school class, which is a private purpose that benefits individual students.
