Suppose that both Brian and Kristen pay $18.42 in order to diminish their checkbook balance. Then, after the payment, their current balances would be
[tex]\begin{gathered} Brian:-23.45+18.42=-5.03 \\ Kristen:18.42-18.42=0 \end{gathered}[/tex]
Therefore, after paying the same amount ($18.42), Kristen's debt has reduced to zero while Brian still owes $5.03.
Thus, Brian owes more money than Kristen.
