A certain radioactive isotope is a by-product of some nuclear reactors. Due to an explosion, a nuclear reactor experiences a massive leak of this radioactive isotope. Fortunately, the isotope has a very short half-life of 7 days. Estimate the percentage of the original amount of the isotope released by the explosion that remains 5 days after the explosion. After 5 days, about % of the isotope remains. (Do not round until the final answer. Then round to the nearest whole number as needed.)
