In the case of Hamilton v. Lanning:

a. the Bankruptcy Court approved respondent's monthly payment of $144 over thirty-six months.

b. Chapter 13 of the Bankruptcy Code provides bankruptcy protection to individuals with regular income whose debts fall within statutory limits.

c. current monthly income is calculated by averaging the debtor's monthly income during a 12-month look-back period.

d. the court stated that it was required to look beyond the Bankruptcy Code to define what Congress meant by the term multiplication.
