Algebra.Com's Answer #251157 by ptaylor(2198) You can put this solution on YOUR website! Let x=time it takes, in hours, to produce 27 spice racks. \n" ); document.write( "If it takes the craftsman 3/4 hr to produce 12 spice racks, then he can produce one spice rack in (3/4)*(1/12) hr or 3/48 hr. so he works at the rate of 3/48 hour per spice rack or 48/3 spice rack per hour \n" ); document.write( "Sooo our equation to solve is: \n" ); document.write( "(48/3)*x=27 or \n" ); document.write( "48x=81 \n" ); document.write( "x=1.6875 hours\r \n" ); document.write( "\n" ); document.write( "Check \n" ); document.write( "If he produces 1 spice rack in 3/48 hr, then he produces 27 spice racks in (3/48)*27 hour or 81/48 hr\r \n" ); document.write( "\n" ); document.write( "Hope this helps----ptaylor \n" ); document.write( " |
