Freelin Conn filed a voluntary petition under Chapter 7 of the Bankruptcy Code on September 30, 2021. Conn listed BancOhio National Bank as having a claim incurred in October 2020 in the amount of $4,000 secured by an eight-year-old automobile. The car is listed as having a market value of $3,500. During the period from June 30, 2021, to September 30, 2021, Conn made three payments totaling $439.17 to BancOhio. May the trustee in bankruptcy set aside those three payments as voidable preferences? Explain.
