Janet and Carl decorate cakes in a bakery. Janet can decorate a cake every 0.24 hour and Carl can decorate a cake every 0.33 hour. If they work together, at what rate are they decorating cakes? Round to the nearest tenth of a cake per hour.
\n" ); document.write( ":
\n" ); document.write( "Let t = how long it take for them to decorate a cake together;
\n" ); document.write( "Let a completed cake = 1
\n" ); document.write( "\"t%2F.24\" + \"t%2F.33\" = 1
\n" ); document.write( ":
\n" ); document.write( "Multiply equation by .24*.33 which is .0792
\n" ); document.write( ".33t + .24t = .0792
\n" ); document.write( ":
\n" ); document.write( ".57t = .0792
\n" ); document.write( "t = \".0792%2F.57\"
\n" ); document.write( "t = .13895 hr per cake (both working)
\n" ); document.write( ";
\n" ); document.write( "That's a rate of \"1%2F.13895\" = 7.2 cakes per hour
\n" ); document.write( "
\n" );
