Answer provided by our tutors
let
t = the number of technicians employed
h = the number of helpers employed
the labor costs for a certain project were $3430 per day for 17 technicians and helpers
t + h = 17
215t + 190h = 3430
by solving the system of equations we find
t = 8 technicians
h = 9 helpers
