Problem $6\mathrm{.}3$: What if$,$ when the Chapter $13$ trustee is reviewing the filed claims, she notices that the All American Pawn Shop has filed a claim indicating that it has a perfected security interest in a $12-$gauge shotgun recently purchased by Eric McPherson. Upon further investigation, the trustee discovers that the shotgun was purchased for $$600,$ its current value is $$400,$ and the balance owed to All America is $$50.$ The trustee knows that the shotgun is nonexempt under state law. Is the $40-$month plan confirmable? Suggestion: Does the introduction of the gun increase the amount of money that would be available to distribute to unsecured creditors in Chapter $7$ and thus cause the plan not to meet the best$-$interest$-$of$-$creditors test? Return to the formula used by the attorney to compute the minimum number of months. If $40$ months is inadequate, how many months is adequate?
