Determine the CFU/mL in the original suspension of E. coli given that:
a) 2300 and 1990 colonies were present when 0.1mL of the 10^-3 dilution was plated in duplicate,
b) 218 & 196 colonies were present when 0.1 mL of the 10^-4 dilution was plated in duplicate, and
c) 18 & 10 colonies were present when 0.1 mL of the 10^-5 dilution was plated in duplicate.
