For a wastewater sample, the three-day biochemical oxygen demand at incubation temperature of 20°C (BOD3 day, 20°C) is estimated as 200 mg/L. Taking the value of the first order BOD reaction rate constant as 0.22 day-1, the five-day BOD (expressed in mg/L) of the wastewater at incubation temperature of 20°C (BOD5 day, 20°C) would be
