Question

An employment agency specializing in temporary construction help pays heavy equipment operators $ 134 per day and general laborers $ 92 per day. If thirty-eight people were hired and the payroll was $ 4756 , how many heavy equipment operators were​ employed? How many​ laborers?

Answer 1

x=heavy equipment

y= general labor

x+y=38

x=38-y

134x + 92y=4756

134(38-y)+92y =4756

5092-134y+92y=4756

-42y = -336

y = -336/-42 = 8

x=38-8=30

check 30*134 =4020

8*92 = 736

4020+736 = 4756

 8 general laborers

30 heavy equipment operators
