You can put this solution on YOUR website! COSTS
Let there be x workers in february
$10 per hour
160 hours per worker
so cost per month for all workers 10*160*x
=$1600x
Fixed cost $18
Total cost = 1600x+18
..
INCOME
Company charges $16/worker/ hour
160 hours = 16*160= $2560 per worker
for x workers income = 2560x
..
Net gain = $10,542
..
Income - expenditure = gain
..
2560x-(1600x+18)= 10,542
2560x-1600x-18=10542
960x=10542+18
960x= 10560
x= 10560/960
x= 11 workers
