An employment agency specializing in temporary construction help pays heavy equipment operators $\$ 137$ per day and general laborers $\$ 94$ per day. If thirty-three people were hired and the payroll was $\$ 4435$, how many heavy equipment operators were employed? How many laborers?
The number of heavy equipment operators hired was The number of general laborers hired was
\(\boxed{\text{The number of heavy equipment operators hired was 31, and the number of general laborers hired was 2}}\)
Step 1 :Let the number of heavy equipment operators be x and the number of general laborers be y. We have two equations:
Step 2 :\(x + y = 33\) (total number of people hired)
Step 3 :\(137x + 94y = 4435\) (total payroll)
Step 4 :Solve the system of linear equations to find the values of x and y.
Step 5 :From the first equation, we can express y in terms of x: \(y = 33 - x\)
Step 6 :Substitute this expression for y into the second equation: \(137x + 94(33 - x) = 4435\)
Step 7 :Simplify the equation: \(137x + 3102 - 94x = 4435\)
Step 8 :Combine like terms: \(43x = 1333\)
Step 9 :Divide by 43: \(x = 31\)
Step 10 :Substitute the value of x back into the expression for y: \(y = 33 - 31\)
Step 11 :Calculate the value of y: \(y = 2\)
Step 12 :\(\boxed{\text{The number of heavy equipment operators hired was 31, and the number of general laborers hired was 2}}\)
