You can put this solution on YOUR website!
First goal is find their actual rates.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let x be the time for Joseph to paint one whole room.
\n" ); document.write( "2x is then time for Sandra to paint one whole room.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "PERSON ______________RATE
\n" ); document.write( "Sandra______________\"1%2F%282x%29\"
\n" ); document.write( "Joseph______________\"1%2Fx\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "What Joseph can do:
\n" ); document.write( "45 minutes is \"3%2F4\" hour.
\n" ); document.write( "\"%281%2Fx%29%2A%283%2F4%29=1%2F4\"------Joseph takes 45 minutes to paint one quarter of a room.
\n" ); document.write( "Now you can find Joseph's rate and Sandra's rate.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%284%2F3%29=4\"
\n" ); document.write( "\"x=4%283%2F4%29\"
\n" ); document.write( "\"x=4\"-------Time in hours for Joseph to paint one room
\n" ); document.write( "meaning his rate is \"1%2F4\" Rooms per Hour.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Sandra's rate is then \"1%2F8\" rooms per hour.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Do the rest!
\n" ); document.write( "
\n" );
