A machine is available 10 hours a day. Each part takes 60 minutes to fabricate and 10 minutes to setup. 10% of the parts made are defective and must go through the machine again to be reworked, during which both setup and fabrication have to be performed again. The machine is idle for any unused time. On average, 4 good parts are made each day. The overall equipment effectiveness of the machine is (round to one decimal places)
