The labor costs for a certain project were $3345 per day for 17 technicians and helpers. If each technician earned $210 per day and each helper earned $185 per day. How many helpers were employed on the project.
Answer provided by our tutors
let 'x' represent the number of helpers, then '17-x' represents the number of technicians
3345 = 185x + 210(17-x)
solving for 'x' we have x=9
there were 9 helpers employed on the project
