Algebra.Com's Answer #79651 by ptaylor(2198) You can put this solution on YOUR website! \n" ); document.write( "AT LEAST YOU GAVE IT A SHOT!! TRY TO FOLLOW MY APPROACH:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Let x=number of days it takes both working together to complete the project\r \n" ); document.write( "\n" ); document.write( "Fugita works at the rate of 50/6 widgets per day (For example, if it takes him 10 days to do 10 cars, then he can do 10/10 or 1 car per day, right?) \n" ); document.write( "Obn works at the rate of 50/8 widgets per day\r \n" ); document.write( "\n" ); document.write( "Together they work at the rate of 50/6+50/8 widgets per day\r \n" ); document.write( "\n" ); document.write( "50/6=200/24 and \n" ); document.write( "50/8=150/24 \n" ); document.write( "so \n" ); document.write( "50/6+50/8=200/24+150/24=350/24=175/12 widgets per day.
