You can put this solution on YOUR website!
Sally's rate is \"+15%2F4+\" sheets / min
\n" ); document.write( "Eric's rate is \"+12%2F5+\" sheets/min
\n" ); document.write( "Jane's rate is \"+7%2F2+\" sheets/min
\n" ); document.write( "---------------------------------
\n" ); document.write( "\"+15%2F4+=+75%2F20+\"
\n" ); document.write( "\"+12%2F5+=+48%2F20+\"
\n" ); document.write( "\"+7%2F2+=+70%2F20+\"
\n" ); document.write( "-------------------
\n" ); document.write( "In \"+20+\" min:
\n" ); document.write( "Add their rates to get rate for \"+20+\" min
\n" ); document.write( "\"+75%2F20+%2B+48%2F20+%2B+70%2F20+=+193%2F20+\"
\n" ); document.write( "Working together, they can fold \"+193+\" sheets
\n" ); document.write( "in \"+20+\" min
\n" ); document.write( "Note that \"+386+=+2%2A193+\"
\n" ); document.write( "It will take them twice as long, or \"+40+\" min
\n" ); document.write( "to fold \"+386+\" sheets
\n" ); document.write( "The answer is (d)
\n" ); document.write( "
