An employment agency specializing in temporary construction help pays heavy equipment operators $ 135 per day and general laborers $ 89per day. If thirty-three people were hired and the payroll was $ 3949how many heavy equipment operators were​ employed? How many​ laborers?The number of heavy equipment operators hired was ____The number of general laborers hired was ____

The answer is:
 Number of heavy equipment operators = 22
 Number of general laborers = 11
 The question can be solved by proposing a system of equations, where:
 Ep= number of heavy equipment operators.
 Tg= number of general labored.
 We have two equations, the first is the cost of hiring heavy equipment operators and general workers.
 
 135Ep+89Tg=3949.
 
 
  The second is the number of operators of heavy equipment and general workers that will be contracted. The total is 33.

 Ep+Tg=33.

 Solving the system of equations we have the answer is:

 Ep=22.
 Tg=11.
