Answer to February 2009 Problem
Lunch Hour Problem

What grade is Charlie Brown in now?
(Assume that his school district has 180 day school years)

Solution to the Problem:

Charlie Brown must be in the first grade.
 

Divide 2,120 by 180 to get 11 school years with a remainder of 140 days.
So, Charlie Brown must have made that statement on the 40th day of first grade. Poor guy!
