\n" );
document.write( "Hi,
\n" );
document.write( "Let x represent the amount of time it would take Julissa.  Then the time it takes Chris would be 2x
\n" );
document.write( "Per hour is the Equalizer***
\n" );
document.write( "1/x + 1/2x = 1/4hr 
\n" );
document.write( "Mulitplying each term on both sides of the equation by 4x so as all denominators = 1
\n" );
document.write( "4 + 2 = x
\n" );
document.write( "6hr = x , the time takes Julissa alone.  Chris's time alone would be 12hr
\n" );
document.write( "checking our answer
\n" );
document.write( "1/6 + 1/12 = 2/12 + 1/12 = 3/12 = 1/4 \n" );
document.write( "

\n" );
