The concentration of E. coli bacteria in a swimming area is monitored after a storm: The time
Question:
The concentration of E. coli bacteria in a swimming area is monitored after a storm:
The time is measured in hours following the end of the storm and the unit CFU is a "colony forming unit" Use this data to estimate.
(a) The concentration at the end of the storm (t = 0) and
(b) The time at which the concentration will reach 200 CFU/100mL. Note that your choice of model should be consistent with the fact that negative concentrations are impossible and that the bacteria concentration always decreases withtime.
