Problema Solution
an employment agency pays heavy equipment operators $134 per day and general laborers $94 per day. If 35 people were hired and the payroll was $4306, how many heavy equipment operators were employed? How many laborers?
Answer provided by our tutors
let
e = the number of equipment operators, e is non-negative integer
g = the number of general laborers, g is non-negative integer
35 people were hired
e + g = 35
the payroll was $4306
134e + 94g = 4306 divide both sides by 2
67e + 47g = 2153
by solving the system of equations
e + g = 35
67e + 47g = 2153
we find
e = 25.4
g = 9.6

we got non-integer roots this means that maybe the numbers in the problem's text are not right because we can not have rational numbers of workers working.
