assuming each day has 8 hours
rate=1job/(25*9*16)== 0.000277777778 jobs/hr
or 0.000277777778=1/(10*12*NumberMachines)
or number machines=1/(10*12* 0.000277777778)=30 machines
rate=1job/(25*9*16)== 0.000277777778 jobs/hr
or 0.000277777778=1/(10*12*NumberMachines)
or number machines=1/(10*12* 0.000277777778)=30 machines
