Answer provided by our tutors
let
h = the number of heavy equipment operators employed
l = the number of laborers employed
39 people were hired
h + l = 39
payroll was $4541
128h + 87l = 4541
by solving the system of equations
h + l = 39
128h + 87l = 4541
we find
h = 18 heavy equipment operators
l = 11 laborers
