\n" );
document.write( "Let x/100 represent the % of that mixture
\n" );
document.write( ".35*2m^3 + .15*6m^3 = x/100*8m^3
\n" );
document.write( "1.60/8m^3 = x/100
\n" );
document.write( ".20 = x/100
\n" );
document.write( "20% = x  the % of sand in this mixture
\n" );
document.write( ".20*8 = 1.6m^3 of sand in that new mixture\r
\n" );
document.write( "\n" );
document.write( "checking our answer
\n" );
document.write( ".7m^3  + .9 m^3 = 1.6m^3 \n" );
