For a radioactive sample with a half-life of about 94 days, storage in a lead lined cabinet for a sufficient length of time assures it will be safe before disposal. A radioactive sample is considered to be safe after 10 half-lives have expired. What percentage of the original radioactivity of the sample remains after this many half- lives? Report answer as a percentage, but do not include the percent symbol. Provide 3 significant digits of precision.
