Jan 31 is the last day in Jan. So the numbers of days into February is just the Date of the month in February.
\n" ); document.write( "For instance, Feb 1 is one day's worth of snow since only one day has past since 31 Jan.
\n" ); document.write( "Feb 7 is 7 days worth of snow.\r
\n" ); document.write( "\n" ); document.write( "You are told the depth d, of snow in inches at the base of one ski resort could be approximated by adding 7 to twice the number of days, t, since January 31st.\r
\n" ); document.write( "\n" ); document.write( "Let d be the DepthOfSnow
\n" ); document.write( "Let t be DateOfMonthInFeb\r
\n" ); document.write( "\n" ); document.write( "So deoth of snow can be modeled as
\n" ); document.write( " $\"d+=+%282%2At%29+%2B+7+\"$ \r
\n" ); document.write( "\n" ); document.write( "Here is a graph of the snow depth
\n" ); document.write( " $\"graph%28400%2C400%2C+-5%2C28%2C+-5%2C100%2C+2x+%2B+7%29\"$ \n" ); document.write( "
