A Micrococcus luteus suspension (125 mL) of unknown concentration was plated on nutrient agar plates. Spread-plating of 100 uL volumes from the bacterial suspension on three replicate plates at 10-5 dilution gave 46, 55, and 39 CFUs

Average CFU count 46.67

Question: Express the average CFU count on a per mL basis
