Freelin Conn filed a voluntary petition under Chapter 7 of the Bankruptcy Code on September 30, 2018. Conn listed BancOhio National Bank as having a claim incurred in October of 2017 in the amount of $4,000 secured by an eight-yearold Oldsmobile. The car is listed as having a market value of

$4,100. During the period from June 30, 2018, to September 30, 2018, Conn made three payments totaling $439.17 to BancOhio.

May the trustee in bankruptcy set aside those three payments as voidable preferences? Explain.
