Assume that after washing your hands, you leave ten bacteria cells on a new bar of soap. You then decide to do a plate count
of the soap after it was left in the soap dish for 24 hours. You dilute 1g of the soap 1:106 and plate it on standard plate
count agar. After 24 hours of incubation, there are 168 colonies. How many bacteria were on the soap? How did they get
there?
