Problema Solution
Marcus and Tony work for the same company. Marcus lays a slab of concrete in 2 hours. Tony lays the same size slab in 5 hours. If both work on the job and the cost of labor is $35.00 per hour, decide what the labor estimate should be.
Answer provided by our tutors
Marcus' rate is 1/2 jobs per hour.
Tony's rate is 1/5 jobs per hour.
Let 'x' represent the number of hours that Marcus and Tony need to work together to finish the job.
The together rate of Marcus and Tony is: 1/x jobs per hour.
1/2 + 1/5 = 1/x

x = 10/7 hr
The estimated cost of the labor is: (10/7)*35 = $50 if together they are paid $35 per hour.
If each of them is paid $35 per hour the total cost of the labor is: 2*(1/7)*35 = $100.
