Let the time taken to do the job by Mark and Rachel together be t hours
\n" ); document.write( "Mark does t/2 portion of the job;
\n" ); document.write( "Rachel does t/4 portion of the job;
\n" ); document.write( "Mark's portion + Rachel's portion = 1
\n" ); document.write( "=> t/2 + t/4 = 1
\n" ); document.write( "=> 2t+t = 4
\n" ); document.write( "=> t = 4/3;
\n" ); document.write( "Time taken by Smith Landscaping Company to finish the job is 4/3 hours.
\n" ); document.write( "Cost of labour is $45 per hour; cost for 4/3 hours = 45(4/3) = $60.
\n" ); document.write( "Answer: $60.00
