Aoife studies a culture flask of microorganisms. The culture flask has a total volume of 1,000 mL. Every day she takes a 50-mL sample and replaces the volume with sterile media so the total volume in the flask remains the same. After 3 days, what percent of original culture remains?  When performing the math, don't forget that every sampling event counts as a dilution. Perform all calculations in a single step using Excel to avoid accumulating rounding error. Report your answer to 2 decimal places.
