Mark and Rachel both work for Smith Landscaping Company. Mark can finish a planting job in 2 hours, while it takes Rachel 4 hours to finish the same job. If mark abd Rachel will work together on the job, and the cost of labor is $45 per housr, what should the labor estimate be? This question is from textbook algebra
You can put this solution on YOUR website! Let the time taken to do the job by Mark and Rachel together be t hours
Mark does t/2 portion of the job;
Rachel does t/4 portion of the job;
Mark's portion + Rachel's portion = 1
=> t/2 + t/4 = 1
=> 2t+t = 4
=> t = 4/3;
Time taken by Smith Landscaping Company to finish the job is 4/3 hours.
Cost of labour is $45 per hour; cost for 4/3 hours = 45(4/3) = $60.
Answer: $60.00
