You can put this solution on YOUR website!
m= # of multiple choice questions
\n" ); document.write( "t= # of true false questions
\n" ); document.write( "this is set up just like money word problems
\n" ); document.write( "m is worth 3
\n" ); document.write( "t is worth 2
\n" ); document.write( " $\"m%2Bt=28\"$ # of ?'s, this says # of multiple choice questions plus # of true false questions equals 28 questions
\n" ); document.write( " $\"3m%2B2t=77\"$ point values, so the total points for m would be 3 times the # of questions and the total points for t would be 2 times the # of true false questions. those two point values added together make 77points.
\n" ); document.write( "

\n" ); document.write( "so substitution or elimination method will work here
\n" ); document.write( "

\n" ); document.write( " $\"m=28-t\"$
\n" ); document.write( " $\"3%2828-t%29%2B2t=77\"$
\n" ); document.write( " $\"84-3t%2B2t=77\"$
\n" ); document.write( " $\"84-t=77\"$
\n" ); document.write( " $\"7-t=0\"$
\n" ); document.write( " $\"highlight%287=t%29\"$
\n" ); document.write( " $\"m=28-t\"$
\n" ); document.write( " $\"m=28-7\"$
\n" ); document.write( " $\"highlight%28m=21%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
