A teacher wants her students to guess the three-digit number that she is thinking.
\n" ); document.write( "She gives these clues:
\n" ); document.write( "• It is divisible by both 3 and 11.
\n" ); document.write( "It must be a multiple of 33
\n" ); document.write( ":
\n" ); document.write( "• If you subtract one, the result is divisible by both 2 and 7.
\n" ); document.write( "Which number is it?
\n" ); document.write( ":
\n" ); document.write( "Lets try an equation on our Ti83, check the table for integer solution
\n" ); document.write( "y = $\"%2833x-1%29%2F%282%2A7%29\"$
\n" ); document.write( "y = 40 when x = 17
\n" ); document.write( "Then 17*33 = 561 is the number
\n" ); document.write( "Subtract 1 and it is indeed divisible by 2 and 7 \n" ); document.write( "

\n" );
