A 10^-4 is performed on a culture of bacteria in order to perform viable plate counts. From the dilution, *0.1 mL* of solution is plated on solid media, and 37 colony forming units grow on the plate.

How many bacteria are in a single mL of the original culture? Express your answer to two decimal places using exponential notation. In exponential notation 540 would be written as 5.E2. Please use an upper-case letter E.

Since only 0.1 mL is put on the plate, this counts as an extra dilution!!!
Any time less than 1 mL is transferred, a dilution is being performed.
Any time more than 1 mL is transferred, a concentration is being performed.
